The star separated from Peter Facinelli, her husband of 11 years, earlier this year (12) and now she's leaning on her one-time TV lover for advice as she copes with life as a single mum.

She tells In Touch magazine, ""Luke has been one of my friends who I can call and talk about stuff and has been through himself.""

Perry went through a painful divorce from his wife Rachel Sharp in 2003.

And Garth is getting the chance to spend quite a bit of time with Perry - the pair has teamed up with fellow Beverly Hills, 90210 stars Jason Priestley and Gabrielle Carteris to front new TV ads for U.S. clothing firm Old Navy.

She adds, ""It's really great to do something together.""
