He's got a thing for costars! Chad Michael Murray is dating actress Sarah Roemer, a source reveals exclusively to Us Weekly.

Murray, 32, and Roemer, 29, currently work together in Crackle's TV series Chosen. The One Tree Hill alum joined the cast last October as new character Jacob Orr. The six half-hour episodes also star Milo Ventimiglia and Brandon Routh.

Murray was most recently linked to his Left Behind costar Nicky Whelan. The couple made their red carpet debut at the Lucky Brand Flagship Store opening in Beverly Hills in October 2013. Us broke news in May that they had split after six months of dating.

Murray ended his seven-year engagement to fiancee Kenzie Dalton in September 2013.

Roemer is best known for The Grudge 2 and starring opposite Shia LaBeouf in 2007's Disturbia. She was once linked to Drew Barrymore's husband Will Kopelman.
