Sigh: why is that hot celebrities are usually taken by other hot celebrities? Is it just a thing in Hollywood where sex bombs are magnetized to other sex bombs? Over the years we've seen the likes of Brad Pitt and Angelia Jolie, Tom Cruise and Katie Holmes, Gwenyth Paltrow and Chris Martin, and Matt Damon and Luciana Barroso. They all look stunning individually - but pair them up into loving couples and suddenly you're staring gobsmacked at a photograph of two people just oozing sophistication and sex appeal. And we're obsessed with them. Why? Well, mainly because it's hard to avoid headlines like 'Kim and Kanye are having another baby' or 'Mila Kunis and Ashton Kutcher are set to marry' - especially when these headlines are splashed all over newspaper front pages, on internet news sites, and across social media pages. But it's also because beauty is entrancing - and when you've got a picture of two well-put together individuals, it's like a double-whammy of gloriousness. And they're always doing something, aren't they? Picking up awards, on a day out with their cute kids, choosing a new house in LA, making amazing speeches at ceremonies. They all seem to be having a wonderful time, and whether it's partly due to being mesmerised, or mainly because the rest of us are all jealous, it seems natural to want to know the ins and outs of these good looking couples' lives. That's not to say we haven't asked ourselves what their relationships are REALLY like away from the cameras. Do they order takeaway in their pyjamas? Do they watch Game of Thrones and get really angry when people die unnecessarily? Do they clean their teeth with each other's toothbrushes? Perhaps that's a project for another time. Regardless of what goes on behind closed doors, here are ten celebrity couples who are incredibly good looking, and who you secretly wish you and your S.O could look like.
