Jaimie Alexander riles up Jennie Garth

OHMYGOSSIP — Jaimie Alexander has caused a spat between Peter Facinelli and his ex-wife Jennie Garth. The former couple have apparently come to blows over Peter’s year-long romance with the Thor star.

“Jennie has tried her best to get along with Jaimie, but Peter’s romance with her just grates on her nerves,” said a source.

Jennie apparently wasn’t happy with Peter when he and Jaimie turned heads by getting overly affectionate with each other at a recent Big Apple event. She went braless in a revealing white blazer and, between smooches, answered a question about Peter’s most romantic gestures toward her by coquettishly saying they were “too graphic” to discuss.

“Jennie tore into Peter over the public lovefest, saying it set a bad example for their daughters, Luca, 16, Lola, 10, and 7-year-old Fiona,” said the insider, reports the National Enquirer.

“But Peter believes what he does with Jaimie is none of Jennie’s business.”

Peter and Jaimie have settled into a $2 million home on the same street in Toluca Lake, Calif., where Jennie, Peter and their girls used to live.

“It’s a knife in Jennie’s heart,” said the source. “But Peter thought it was a great idea for their daughters to stay in the same neighborhood. Just when it looks like they’ve made peace, one of them does something to antagonize the other.”
