Love is a peculiar thing. Hollywood love… well… now, that's a whole new level of weird. Not only is it completely incestuous (think: six shags of separation), it is also about as enduring as Steven Segal's latest action flick.

Needless to say, finding odd in a world of celluloid dysfunction is tricky. But not impossible. Yip, there are some Hollywood hook-ups so utterly inexplicable that they deserve special mention…

Beauty and the Beast

Do you know what Lyle Lovett looks like? No. There is a reason for this. In fact, it may very well be the reason he became a singer — looks were never going to win him any fans. How about Julia Roberts?

Shallow I know, but when the only thing a couple seems to have in common is a perm, it's just not likely to last. Roberts and Lovett (ten years her senior) eloped and married in 1993 after only knowing each other for three weeks. Not-so-surprisingly, they got divorced two years later. Hairstyles come and go, but love…

Equally baffling was the coupling of supermodel Claudia Schiffer and magician David Copperfield. Ah yes, I know what you are thinking: mystery, magnetism… plain old-fashioned hypnotism? But I have a slightly less supernatural answer: cash. In his heyday, Copperfield was raking in a cool $57-million a year. Now that is attractive.

The two met in Berlin in 1993 (hmm… that year again) at a celebrity gala. Copperfield called Schiffer on stage to take part in a mind-reading act (yes, yes, I know what you're thinking). They were engaged after three weeks, but stayed that way until they split up in 1999.

And now, on to the 21st century — Marilyn Manson and Evan Rachel Wood. Marilyn Manson (real name: Brian Warner) and his ex-wife Dita Von Teese (Heather Sweet) was already pretty confusing, but at least she was a suitable age.

Manson (38 at the time) met the barely legal former child-star (19) when he asked her to appear in his horror film 'Phantasmagora: The Visions of Lewis Carroll' and the two discovered that they were kindred spirits. The blonde dyed her hair, donned black clothes and thick eyeliner and the couple got matching black heart tattoos. They split up two years later (2008), but are rumoured to be rekindling their dark and twisty love.

How did that happen?

Not all Hollywood romances prompt smirks (see above), holier-than-thou-looks, or gag reflexes (see below), some are just, well… weird. You know: baffled expressions and exclamations of 'Huh? How did that happen?'

Older men going for sweet young girls is pretty much a given, but famous handsome young men shacking up with (admittedly gorgeous) older women just doesn't follow the Hollywood script.

Case in point: Ashton Kutcher and Demi Moore. Sure, she may have the surgically-enhanced body of a nubile teenager, but there will still come that point when Demi is 60, Ashton is 40, and Demi's daughters are in their 30s. But hey, how many Hollywood marriages last that long anyway?

In the meantime, the couple — who started dating in 2003 and married in 2005 — is showing the world that age doesn't matter when you have Kabbalah, heaps of money, and a good plastic surgeon.

While Demi traded in an ageing action hero for a younger model, Lindsay Lohan traded in men entirely. Yip, the child-star-turned-train-wreck who has been linked to a long list of men ever since she graduated from Disney, suddenly decided that women were more her thing.

After a brief period of media speculation, Lindsay (22) and DJ Samantha Ronson (31) stepped out of the… uh… closet as a couple. Barring the gender of her latest partner, not much has changed — LiLo still has a weight problem, a substance abuse problem, and a problem keeping her private life, well, private.
