Ashley Olsen & Justin Bartha Split

Ashley Olsen Justin Bartha

Just weeks after Mary-Kate Olsen breaks up with her boyfriend, Ashley becomes single too.

Even at the age of 24, do super-star twins Ashley and Mary-Kate Olsen still do everything together? In addition to running their multi-million fashion empire, both twins were in serious relationships up until recently. Mary-Kate began dating artist Nate Lowman in 2008 after meeting through mutual friends, but confirmed that the relationship was over at the end of February. And now, Ashley Olsen, who had also been in a steady relationship with The Hangover actor Justin Bartha, has reportedly ended her relationship as well, just a few weeks after MK's.

According to US Magazine, Justin had supposedly been close to proposing to Ashley in the past, but something clearly went wayside.

"It's over," said a friend of the couple, simply. Justin Bartha To Propose To Ashley Olsen?

Although given the low-key nature of their relationship, we don't expect a lot of details to emerge about their breakup. However, it does make us wonder if Mary-Kate's breakup may have had an effect on Ashley's. Certainly, if you've just become newly single, you would want to cry on your twin sister/best friend's shoulder. But did Mary-Kate push a wavering Ashley to end her relationship? (Reportedly, Ashley and Justin were loft-shopping in New York together on 3 months ago, so any relationship problems were likely new.)

Or did Justin, who was an unknown actor when he first met Ashley, and has now achieved minor stardom thanks to his role in the popular movie, The Hangover, and the upcoming Hangover sequel, suddenly decide that he wanted to take advantage of his new-found celebrity as a single man?

What do you think, CelebLovers? Did Mary-Kate play a role in Ashley's breakup? Or was the timing merely coincidental? Mary-Kate Olsen's...Not Engaged
