Yo-Yo Celebs

The showbusiness pressure cooker seems to drive most celeb couples to act in fairly irrational ways. Here's a few of the couples who seem to be on-again, off-again, on again.

Billy and Kelly seemed to be one star couple who were solid as a rock - but their sudden split after four years surprised everyone. Now they're back together again and seemingly getting hitched

One of the more bizarre celeb entanglements was bad boy rapper Marshall Mathers III and his high-school sweetheart Kim. As well as twice being married and divorced, Eminem has rapped about his tumultuous marriage, often fantasising about murdering his ex and abusing a Kim styled blow-up doll on stage

It's been a fairly rocky road for the slightly grubby couple since they met in 2005. Blake was dumped when it was found he was cheating on the bee-hived wonder, but after a reconciliation they were married in 2007. Of course the law has now intervened in their matrimonial bliss

In the running for yo-yo record holders are Jess and John who hooked up and then split up an estimated nine times during the span of their relationship. After they split for good in 2007, John moved onto Cameron Diaz before settling on Jennifer Anniston

It was at Kate's 31st birthday party that Potty Pete finally convinced the girl of his dreams, Kate, that he was the one for her. They suffered a series of supposed splits and reconciliations and then in April 2007 he announced from stage that Moss was his fiancée, but by July it was all over

They met on the set of The Fantastic Four, but the course of true love was not so fantastic for this Hollywood sex symbol and her producer beau. They called it a day, only to reconcile frequently until late last year Alba announced she was pregnant and the couple finally wed in May of this year

Diddy's long-term girlfriend was on the scene for ten years and the couple had three kids together. Their first split occurred when the rapper started a high-profile affair with Jennifer Lopez, but Kim 'waited for him' and they reconciled. They split again in July of last year and Diddy has been linked romantically to a number of available ladies

The Welsh songstress and the former EastEnder met in the jungle - causing tongues to wag during their stay together on I'm a Celebrity... Marc split from his girlfriend and once the show was over, the couple hooked up. Their was a distinct lack of surprise when the unlikely pair announced they had split in February - but consternation when it was revealed they have since reunited

It was hardly Romeo and Juliet when the former Baywatch star and rapper/rocker hooked up in 2002 - they had a number of false starts until they finally split in 2003. There were a number of eyebrows raised when the couple announced their engagement and subsequently wed in 2006. They divorced four months later

Girls Aloud singer Nadine seemed to give up everything to be with her man - putting her music career on hold and moving to LA to be closer to the actor. But when he was pictured with a mystery woman, Jesse was dumped and Nadine returned to Blighty. Jesse has since been tattooed with Nadine's image and he’s begged her back. They've been seen together but refuse to confirm the status of their relationship

Setting the benchmark for yo-yo celeb relationships were this legendary Hollywood couple who were married twice, in 1974 and 1976. Their classic depiction of a warring couple in ‘Who's Afraid of Virginia Woolf?’ is often thought to mirror their rocky relationship. Burton went on to marry five times; Taylor topped him with eight trips up the aisle
