In a candid interview with Red magazine, the 50-year-old star says that her past struggles with addiction and the death of her sister Caroline in 2012, means she can cope with anything.
She tells the magazine: “’[You] need to experience difficulty to learn how to be resilient. If you haven’t been through anything difficult, the minute you do, it will hit you like a freight train and you won’t know what to do because you’ve never been given the tools to deal with it.
“When I think of all the stuff that happened with my mum in my childhood, and the drugs and the alcohol, and my sister dying, and knowing I got through all that… all of those things make you think ‘throw anything at me – I’ll be okay’.
“It might be hard, but I do feel I could deal with anything.”
“I dance a lot better without booze than I did with booze,” she says. “If you don’t have to give up booze, then for God’s sake, don’t give up booze.
“I had to grieve not drinking. That was so sad. But I knew that alcohol was the gateway to drugs for me, and it would still be the gateway. It’s just not worth it.”

Despite her impending divorce, the mum-of-three says she’s in a “good place”.
“I’ve realised that I don’t need much. When I was in my 30s, I was like, ‘I want the house, I want the dog, I want the car.’ But I don’t need it. I don’t really want it.”
Last week, Davina set the record straight following claims she is set to pay £2.5 million to her ex-husband for a “quickie” divorce.
Shutting down the report on Twitter, she wrote: “Just for the record I have not and never will discuss my divorce .. money /kids/terms NONE of it with the press so whatever is out there is not from me ( and is rubbish) This is to protect our kids.”

Celebs Who Handled Their Splits Like A Boss
Cameron Diaz and Justin Timberlake(01 of11)

Let's be honest, break-ups can be messy, particularly in the glare of the spotlight, so it's good to see when two celebrities can put their differences aside and still be friends, as Cameron and Justin did - even eventually going on to star in 'Bad Teacher' together.

Harry Styles(02 of11)

No one is exactly sure what happened between Taylor Swift and Harry Styles, but even after she appeared to mock him during an awards show performance, he's had nothing but good things to say about her and her music in the press.
Whether he's genuinely happy for her, or he's simply killing her with kindness is unclear, but either way, we could all learn a thing or two from Hazza. (credit:Kevin Mazur via Getty Images)
Jennifer Aniston(03 of11)

And speaking of how to flawlessly handle a break-up... The media coverage surrounding Jennifer Aniston for the decade after her split from Brad Pitt, was often unnecessary, cruel and steeped in sexism.
Through it all, though, she kept her head high, continued working and, more importantly, smiling away, despite what was said about her in the press.
Now she's one of the highest-paid actresses in the world, and is married to her long-time partner, Justin Theroux. (credit:Steve Granitz via Getty Images)
Mariah Carey(04 of11)

When she and the father of her two children, Nick Cannon, split, Mariah was determined not to give the press the dirt they were craving.
So much so, when approached by a TMZ reporter, Mimi said simply: "Oh, it's much too hot to talk."
Flawless. (credit:Ethan Miller via Getty Images)

Elin Nordegren - better known as the former Mrs Tiger Woods - is our personal break-up hero.
So, your husband has repeatedly cheated on you and the world's media are talking about it? Whatever.
Elin's attitude throughout the scandal was flawless: head down, sunglasses on ... and just wait for that divorce settlement to roll in. Props to you, Elin. (credit:Orlando Sentinel via Getty Images)

However, sometimes it's difficult to pretend you're anything other than hurt. And do you know what? That's OK too.
In showing her vulnerable side in her documentary film, 'Part Of Me', Katy undoubtedly assured a lot of people that it's not about how hard you fall, it's how you get back up again. (credit:JB Lacroix via Getty Images)
Gwyneth Paltrow(07 of11)

Gwyneth Paltrow hasn't had a bad word to say about Chris Martin ever since they "consciously uncoupled" in 2014, and even spoke favourably about his relationship with Jennifer Lawrence.
Instead, she focused on her own career, her family and friends, and the continuing growth of her site, Goop. Now that's how you tackle a break-up like a boss. (credit:Sonia Moskowitz via Getty Images)
Katie Price(08 of11)

Perhaps not quite to this extent, but sometimes a night out with your friends can be just the thing to get you through a break-up, as Katie Price proved when she flew to Ibiza, shortly after splitting up from Peter Andre. (credit:Dave Wood via Getty Images)
Jennifer Lopez(09 of11)

Determined not to let anyone paint her as a victim, J-Lo bounced back from her split with Marc Anthony by getting together with a far younger man.
Nice one, Jen. (credit:Gregg DeGuire via Getty Images)
Perrie Edwards(10 of11)

Similarly, the world of entertainment journalism seemed determined to paint Perrie Edwards as a victim when she broke up with ex-fiancé Zayn Malik, particularly when he quickly got together with Gigi Hadid.
How did she respond to that? With independence anthem 'Shout Out To My Ex', which quickly topped the UK singles chart, and bagged Little Mix their first ever Brit Award. (credit:Karwai Tang via Getty Images)
Adele(11 of11)

And then, of course, there's Adele, who managed to turn her disastrous break-up to her advantage and bag herself a wheelbarrow of Grammys, which we have all the admiration in the world for.
