In real life!

Guess these two didn't have a romantic Valentine's Day..or a genuinely good one.

Sophia Bush, 29, and Austin Nichols, 31, who have been on-and-off for six years are calling it quits.

A source reveals inside this Friday's issue of Us Weekly that the actress split with Nichols "because she didn't think he was the one. She's moving on."

Good to know she doesn't believe in settling for Mr. Wrong. This isn't the first time she's dated a cast member. Bush's past relationships have also been with her fellow One Tree Hill co-stars.

Back in 2005, she and Chad Michael Murray got hitched. The two dated for two years but the marriage lasted only five months amidst reports of Murray's infidelity. 

Ouch....but at least it lasted longer than Kim's marriage!

In 2008, James Lafferty and Bush dated but that ended some time in 2009. 

Awkward..... there must have been a lot of cat fights on set.  Maybe it's best she stays away from dating any more of her fellow actors... especially her One Tree Hill co-stars. 

The worst part of all this? Sophia and Nichols are still married on the TV show. DOUBLE AWKWARD!

The show's finale is set to air on April 4th.
