New romance alert!
"They held hands and quietly stole kisses throughout the night," an eyewitness told Us Weekly about the pair.
Jaimie, 28, has co-starred with Peter, 38, in episodes of his television show Nurse Jackie and was also in Loosies, a film he wrote the screenplay for.
The striking actress and the Twilight star have been quietly dating for a few months.
Meanwhile, Jennie appears to have moved on, and has been rocking her new toned and slim body on red carpets — most recently wowing in a red dress at the GQ party in Los Angeles on Tuesday.
As RadarOnline.com previously reported, Peter and Jennie split up earlier this year after 11 years of marriage.
They have three children together.
