The benefit of hindsight is a great thing, especially when it comes to relationships, as it appears Russell Brand has found out for himself.
The comic has reportedly sent ex-wife Katy Perry an email admitting he "gave up" on their 14 month marriage too soon, branding it a "mistake" and begging for a second chance.
Russ - who filed for divorce from Katy in December - was said to be "seething with jealousy" after seeing pictures of her with new boyfriend - Florence And The Machine guitarist Robert Ackroyd - at last month's Coachella Festival.
According to Grazia magazine, it prompted him to re-evaluate his relationship with the singer.
A source close to the star told the mag: "Word has it Russell was 'seething with jealousy' when he saw pictures of her with Rob. He apparently feels he gave up on their relationship too easily.
"It's fair to say that Russell only wishes Katy Perry happiness but perhaps he should have realised just how special his wife was when he was married to her rather than five months later."
Only over the weekend, Russell took an audience member to task after they heckled him during one of his stand-up gigs.
The comic unleashed a string of insults at them after they yelled Katy's name.
An eyewitness told Life And Style magazine: "He went on to attack everything from how good he thought the guy would be in bed to accusing him of being impotent. It must have been humiliating for the guy; it seemed to go on forever.
"Eventually he pulled it together and got back on the stage, and being Russell, he told the guy he'd just torn apart that he loved him."
It was also recently reported that Russell was dating David Hassellhoff's ex-girlfriend Anouska De Georgiou.
The pair were spotted hand-in-hand last month on their way to a charity fundraiser in LA, with a source telling The Sun: "Anouska is a good match for Russell as she's got a fiery personality.
"It won't be too difficult for her dealing with the limelight. She had a pretty serious relationship with The Hoff a couple of years ago. They were together for almost a year, which in LA is a big deal."
But where will these latest revelations leave the couple?
