Awwwww, this news makes me sad. Sophia Bush and her long-time boyfriend Austin Nichols have called it quits.

The 29-year-old actress has been dating Austin, 31, since they co-starred on One Tree Hill together.

A source told Us Weekly Sophia “didn’t think he was the one,” and added “she’s moving on.”

She was previously married to OTH actor Chad Michael Murray before they divorced in 2006.

She remained quiet about dating Austin until 2010, when she confirmed they had been dating for four years.

Who’s she going to date now that OTH is coming to an end after nine years?

The celebs came out to support a cause at the Promise Charity Gala held at Espace, New York City.

The guest included Justin Bieber, Maria Menounos, Adrian Grenier, Shaquille O’Neal, Usher and Sophia Bush.

‘The Green Hornet’ premiered in Hollywood last night, and all the movie’s stars were out in full force.

Seth Rogen stepped out with his fiance, while Sophia Bush and Cameron Diaz hit the red carpet solo (where’s A-Rod?). Tom Green made an appearance…where’s he been lately?
