Lots of celebrity couples broke up in 2011 ... how many can you remember? We shouldn't kick up our heels at evidence that the famous and well-funded are as human and fallible as ordinary folk. But it's pretty hard not to.
"Marriage is one of the most difficult things in the world."
Yes, Ashton, yes it is.
Kutcher -- who allegedly spent his and Demi's sixth anniversary fooling around with a San Diego party receptionist -- was among those thinking deep, end-of-relationship thoughts as 2011 drew toward a close.
ScarJo had a tough 2011 on the personal front. She had a tough 2010 too, splitting up with Ryan "Sexiest Man Alive" Reynolds. She followed that this year with a split from Sean "I'm 24 Years Older Than You" Penn. Topping it all off, photos of her bare backside and upper body, hacked from her phone, were trotted out all over the Internet. Those pictures weren't for 24 Years Older Than You, by the way; they were for then-husband Sexiest Man Alive.
Meanwhile, Kat Von D, whose upper body has been seen bare without the hassle of hacking, found herself planning a summer wedding, then later counting the number of alleged hook-ups by fiance Jesse James while they were together.
"Today I encountered the 19th girl to add to the list of people Jesse cheated on me with during this last year ..." the tattoo artist wrote in mid-November on Facebook.
Which is worse: someone cheating on you behind your back, or someone who doesn't back your behind? Kris Humphries allegedly said Kim Kardashian had a fat behind.
And you know where that couple landed -- the same place as all the other couples in our gallery: Splitsville.
