Celebrity odd couples

Johnny Borrell and Emma Watson

Butter-wouldn't-melt Harry Potter star Emma, 18, was snapped around town earlier this year with the 28-year-old Razorlight rocker. Borrell is no stranger to dating former child stars – his ex is Kirsten Dunst – but Emma doesn't seem an obvious girlfriend for Pete Doherty's ex best mate.

Ulrika Jonsson and Sven-Goran Eriksson

The former telly babe had slipped off the showbiz radar when her affair with the nerdy, middle-aged England football manager helped push her back into the limelight in 2002. Which leads us to wonder: what on earth did fading celeb Ulrika see in millionaire headline-magnet Sven?

Jennifer Lopez and Marc Antony

It didn't work out for J-Lo and R&B hunk P Diddy, or Hollywood hunk Ben Affleck, or dancer hunk Cris Judd. So she hooked up with nerdy lil' Latin crooner Marc instead, and struck love gold. Marc must have huge charm (or something else): his previous wife was a Miss Universe.

Woody Allen and Soon-Yi Previn

When these two got together a decade and a half ago, moralists everywhere frothed in outrage. Soon-Yi, then a teenager, was the adopted daughter of Woody's long-term partner Mia Farrow. But they married when she was 22 and he was 57, and they're still very much together, 11 years and two kids later.

Sophie Dahl and Jamie Cullum

Little Eva Longoria doesn't raise many eyebrows as the amour of basketballer Tony Parker, even though she's more than a foot shorter (and seven years older) than him. But switch the heights, and suddenly everyone does a double take – such as when model Sophie Dahl (6ft) started dating jazz thimble Jamie Cullum (5ft 4in). Their kids could be the world's most gorgeous pianists.

Lulu and Jason Orange

The 59-year-old wee Scot guested on Take That's 1993 hit Relight My Fire, and rumours soon abounded that Jason and Lulu enjoyed a touch of extra-curricular fire lighting. In a recent TV documentary, Jase said: 'If Lulu says I gave her one, and she says I was great, that's fine by me.'

Michael Jackson and Lisa-Marie Presley

Publicity stunt? Neither Elvis's little girl nor the oddly-featured former pop king needed the column inches when they married in 1995. But when Lisa Marie insisted on ABC: 'Do we have sex? Yes! Yes! Yes!', many wondered whether the lady doth protest too much. Seven months after the wedding, she filed for divorce.
