Lifetime has tapped Heather Locklear - the star of its most-watched original movie ever, Nora Robert's Angels Fall - for a holiday-themed pic based on the Jane Porter novel Flirting with 40. In it, TV's former Sammy "No Man Too Old" Jo will play a divorced mother of two who enters into an unexpected romance with a much younger man.

Flirting with 40 is eyed for a May-December premiere.
