Tyler Jacob Moore and Emmy Rossum split

Tyler Jacob Moore and Emmy Rossum split, Actors Emmy Rossum and Tyler Jacob Moore have been dating since 2011 when their show 'Shameless' premiered. Not the couple go their separate ways.

Emmy Rossum and Tyler Jacob Moore have called it quits after dating for two years, reports Us Weekly. The "Shameless" co-stars first began dating in 2011 when the Showtime drama first premiered.

A source revealed that actress Emmy Rossum is no longer dating her 'Shameless' co-star. Instead, she is focusing on her work.

Rossum, who plays the character Fiona Gallager in the hit series, described her ideal date to Us Weekly on June 4 but it didn't include Moore.

"Honestly, like, a movie and Applebee's. Just keep it simple," the 26-year-old actress said. "I want to talk to you and know what you thought about the movie afterwards. Because discussing what I do and art and movies and museum exhibitions - that's one of the biggest pleasures in life is talking about things, so I just want to talk to somebody and see what they think."

There's no telling what caused the breakup between Rossum and Moore, 30, who plays Toni Markovich in "Shameless," but a source did some talking to the magazine when confirming the couple are no longer an item.

The actors smooch in happier times earlier this year at a basketball game in Los Angeles.

Rossum was previously linked to Counting Crows frontman Adam Duritz, who she reportedly dated for a year. She was also married to music executive Justin Siegel from 2008 to 2010.

Now it seems the New York City native's focus is all about work. Hope you all had a happy and safe 4th," she tweeted Friday. "Back to work starting tonight on a new film called 'Curfew' in my home state New York."
