"And Jen needs a change of scenery to help get over the funk she's been in since she and Vince [Vaughn] broke up. She's looking forward to the new social scene she'll get to enjoy when she settles into New York!� says the insider.

While in New York, she also spent time with friends, dining at one of her favorite restaurants, Nobu, before jetting out to LA this weekend.
