Jen and Vince may have split in December but they clearly have remained good friends. In fact, Vince was present at Jen's 38th birthday party [1] this weekend which was held at Courteney Cox's Beverly Hills home. Vince was apparently there for 2 hours with other friends like Sandra Oh and David Spade. In these pics he is headed to work but not before a little stretch and a smoke. Let's hope he dressed up a little more for Jen this weekend.
