Newly-engaged Carmen Electra is giving weary mums a few sex tips to keep the romance alive in their marriage - just in time for America's Mother's Day on Sunday.

 The actress/model tells the new issue of Cosmopolitan that women should always be prepared for sex - even if that means keeping a "sexiness kit" at work or in the car.

 Electra claims the ideal kit should include "perfume, lip gloss, and a pair of heels."

 And she adds, "Being flirty is a way of letting a guy know you're interested without making a fool of yourself."
