Jamie-Lynn Sigler and Mark Sanchez: Splitsville

They’ve been dating for three months, but now Jamie-Lynn Sigler and Mark Sanchez have called off their relationship.

The “Entourage” babe and the New York Jets stud couldn’t seem to make things work given their crazy schedules.

An insider explained, “They split because they were both just heading in very different directions. He’s 23 and wants to have fun and win football games. She’s 29 and wants to date a nice, honest guy. I think he was a little young for her.”

Now single, Jamie-Lynn is free to head to New York City for her off-Broadway gig “Love Loss and What I Wore” while Mark will be training with his football team.
