Five months after her husband of 11 years — Twilight actor Peter Facinelli — left her, Jennie Garth tells In Touch that she has found a surprising rock to lean on: her former Beverly Hills, 90210 co-star Luke Perry, who, she says, has guided her through the split.

“Luke has been one of my friends who I can call and talk about stuff and has been through something himself,” Jennie tells In Touchon newsstands now. The 46-year-old actor and proud father of Jack, 15, and Sophie, 12, dealt with his own divorce In 2003.

The pair, who famously played lovebirds Kelly Taylor and Dylan McKay on the hit ’90s series, are teaming up professionally in a new Old Navy commercial and a new television show they’re co-producing.

“Luke’s one of my best friends,” Jennie, 40, tells In Touch. “It’s really great to do something together.”
