Emmy Rossum Splits From Boyfriend, "Shameless" Co-Star

"Shameless" star Emmy Rossum, 26, has just split with her co-star boyfriend of two years, Tyler Jacob Moore, 30. His character had "lusted" after her character on the gritty drama series, says the UK's Daily Mail, but their storylines never linked romantically. 

Off the screen, it was a different story. They started dating in 2011, prior to which she was married to music executive Justin Siegel up until 2009.

Tabloids report that Rossum seemed to be in good spirits over the Independence Day holiday, celebrating in the ritzy Hamptons, a New York getaway, telling friends she was "single again."
