So far, 2011 hasn’t been a banner year for Jaime Pressly.

Less than three weeks after the My Name is Earl actress, 33, was arrested on suspicion of a DUI, multiple sources confirm she and entertainment lawyer husband Simran Singh are calling it quits.

“They are done,” one insider tells UsMagazine.com of the pair, who wed in September 2009.

Adds another, “It’s over. I don’t think they have officially filed anything yet though.”

Continues the second source, “I think it comes down to she married this guy too fast. He seemed like a good guy but he is super full of himself and puts her down for everything. He picks fights with her for any little thing.”

Thank You!

The insider adds that Pressly is most heartbroken over how the separation will affect her three-year-old son Dezi (with ex-fiance Eric Cubiche.)

“She doesn’t want to confuse him,” says the source. “Her baby is her top priority. She is a strong girl though and she will come out of this fine.”
