Former co-stars Shannen Doherty and Ian Ziering came out to celebrate with her at the London Hotel in West Hollywood. We thought Jennie and Shannen hated each other? 

Jennie was looking fabulous in her black dress as she also celebrated her 40th birthday, and looking like she had not a care in the world about her recent split from Peter Facinelli.

Also in attendance were her little co-stars: daughters Luca, Lola and Fiona. 

When asked if she was worried about putting her children on TV, Jennie told OK!: "No, we were very protective of our girls early on, but believe me — to get to my kids, it would be like getting through Fort Knox. I feel like my children are safe. I wouldn’t put them in a position where they wouldn’t be safe."
