The couple welcomed their first child Pearl in April, but just three weeks later, Jack found out he had multiple sclerosis.
The newlyweds have shared snaps of their intimate Hawaiian ceremony - - which took place last week with the mag and they also spoke about overcoming Jack's illness.
"We've dealt with a lifetime's worth of problems in one year," Lisa told the magazine. "We've got through it all and I just know we'll be together forever."
The former wildchild of the Osbourne clan added: "I feel like marriage will make our bond even stronger. Having Pearl and now marrying Lisa are just the best things ever. They have changed my life."
Sharon told Hello!: "He is the happiest he has ever been. In less than a year and a half, the things that Jack has been through. It's unbelievable.
"He has found his partner in life and he is so happy. That makes me happy.
"It is lovely because the family is getting bigger. Now we have Pearl and Lisa - we adore Lisa."
The couple married last week on the island of Hualalai, after previously denying they were on the island to marry, but instead celebrating Sharon's 60th birthday.
They exchanged vows they had written themselves in front of guests who included Jack's sister Kelly.
"We wanted it to be intimate and all about us and our families," Jack added.
Congrats to the happy couple!

> IN PICS: CELEB FILFs
R&B megastar Usher, father to Naviyd Ely and Usher V (have there been that many Ushers?), has had a bit of a reputation for playing away in the past but since he's got more sexy dance moves than Justin Timberlake, we reckon we could overlook the odd indiscretion. And unlike the Trousersnake, Usher's single... woohoo! (Pic: PA)
After ditching Gwynnie, having a brief fling with J-Lo and making a string of heinous movies (Gigli, Pearl Harbour, Daredevil... need we say more?) Ben Affleck finally stopped messing about and settled down with the gorgeous Jennifer Garner. Two children later and Ben's turned director and family man... which means we've finally forgiven him for the 'Bennifer' mistake and welcomed him into the world of A-list FILFs. (Pic: PA)
If Victoria's the Queen of the WAGs, then David Beckham has to be the King of the FILFs. He has emerged from several cheating allegations without even a hint of divorce and is fiercely loyal to his stick-thin wife (not that we're bitter). Not only does he make girls everywhere go gooey by getting snapped messing about with his three boys, Brooklyn, Cruz and Romeo as well as his gorgeous daughter Harper Seven, but he looks astonishingly fit in Armani underwear, making women everywhere go... well, you get the idea. (Pic: PA)
It takes a seriously good man to cope with a top-class movie career, the hottest woman in Hollywood and six kids. But Brad Pitt does it all while effortlessly maintaining his 'too cool for school' aura. Not only did he take on Ange's two adopted children, he fathered three of his own and adopted another... and since he's still super hot even though he's approaching his 50s, we reckon Brad's the über-FILF. (Pic: PA)
Like Brad, Johnny Depp is in his late forties, though you'd ever know it. Fabulous skin, Brando-style mumbling, quirky movie roles... it's no wonder Winona Ryder, Kate Moss and current love Vanessa Paradis all fell for his charms. Johnny keeps his two children, Lily-Rose and John, well away from the glare of the media but he'll happily turn up unannounced at a school dressed as Captain Jack Sparrow just to surprise a nine-year-old fan. What's not to like? (Pic: PA)
The Irish rogue might have two children by two different women (both of whom he dumped) and a sex tape that just will not go away, but bad boy Colin Farrell's rugged good looks mean he sneaks into the realm of FILFdom. He might have a foul mouth but then, it's that air of danger that puts him on the list. (Pic: PA)
Ever since Mark Owen was exposed as the Take That member who just can't keep it in his pants, quiet man-band-member Howard Donald has started to look all the more appealing. The father-of-two has grown into his rugged looks as the years have passed... and check out his on-stage acrobatics! Of course Howard has had his own tabloid exposé, but the events concerned happened a while ago now and we'd like to think he's older and wiser these days. (Pic: PA)
One for the mothering types now - he may not be to everyone's taste but, since the tragic death of Jade Goody, Jeff's become a single father to Bobby Jack and Freddy. With his chirpy Essex charm, cheeky grin and devotion to his children, he's definitely got FILF potential... even if we do feel the need to ruffle his hair. (Pic: PA)
We've no idea how it happened but Dannii Minogue went from being Kylie's sister to X Factor style queen in the blink of an eye and pulled 6ft 4in former rugby player Kris Smith in the process. When they first met, Dannii thought he was gay - to be honest, we wish it had stayed that way because with that face and body, we definitely would. (Pic: PA)
Ever since he joined in on Sarah Silverman's comedy song 'I'm f***ing Matt Damon', the Good Will Hunting star has found a special place in our hearts. He was voted the Sexiest Man Alive by People magazine back in 2007, largely thanks to the Bourne trilogy, and the fact that he has a wife and three daughters proves he's got staying power. And we like them apples very much indeed. (Pic: PA)
Possibly the only reason we put up with disappointing rom-coms such as The Wedding Planner and How to Lose a Guy in 10 Days is the sight of Matthew's abs. The father-of-two oozes 'surfer dude' appeal - back in 1999, he was arrested in the early hours of the morning and charged with disturbing the peace after being found playing the bongo drums in the nude. 'Nuff said. (Pic: PA)
Now for some homegrown FILF talent - forget the ponytail and elf ears from Lord of the Rings, it was the sight of Orlando in a billowing white shirt in Pirates of the Caribbean that really got hearts racing. One secret wedding later (to supermodel Miranda Kerr) and Orlando's became a father to baby Flynn. Snaps of Bloom with his new baby boy were enough to melt even the stoniest of hearts. (Pic: PA)
Millions of screaming women were hoping Ricky would one day be talking about them when he sang She Bangs, but it wasn't to be because the "hot-blooded Puerto Rican" was Livin' La Vida Loca with a boyfriend. Even so Ricky, who has twin boys from a surrogate mother, can still gyrate with the best of 'em and if he ever has a sexuality wobble, we'll be there dirty dancing like a shot. (Pic: PA)
The famous footballing winker isn't a favourite with England fans but Ronaldo was probably the only reason most women tuned in for the World Cup last year. And since he announced that he had unexpectedly become a father, we just can't stop picturing Athena's famous 'Man and Baby' poster. The chiselled features, ripped torso... yeah, we could definitely get FILFy with Cristiano. (Pic: PA)
Back in his Crazy days we never thought much of Seal - but since he married Heidi Klum and became a father-of-four, we're starting to see the attraction. Every year, he and Heidi renew their vows and have a big party but spend an hour alone with the family reading vows to each other as the sun sets. See what we mean? (Pic: PA)
