When Sophia Bush and Austin Nichols called it quits in February, "One Tree Hill" fans were devastated. But it appears that devastation might be over!

Bush, who is now starring on the CBS sitcom "Partners," was spotted hugging her ex, and former co-star, while leaving the gym this afternoon (September 25). Nichols even stuck around while Bush grabbed a cup of joe at Coffee Commissary in West Hollywood. So are these two getting back together?

Bush reportedly ended their six-year relationship, with a source telling Us Weekly (via the Daily Mail) that she didn't think Nichols "was the one," adding, "she's moving on." Bush was also married to another "One Tree Hill" co-star, Chad Michael Murray, but the pair divorced in December 2006.

But, things might be heating up again for Bush and Nichols. By the looks of these photos, and the sound of some tweets the pair have been exchanging, they might be rekindling their romance.

"I know this slammin hot babe, @SophiaBush. Her new show is on tonight on CBS. Watch it or I will hunt you down," Nichols tweeted last night before the series premiere of "Partners."

"Aw shucks," Bush replied.

Check out pictures of the pair cozying up this afternoon!
