Heather Locklear's Bikini Beach Shoot

Looking terrific at 46-years-young, Heather Locklear hit the sandy beaches of Hawaii while filming her new movie "Flirting with 40" on Wednesday (April 23).

According to an onlooker, "Heather spent all day filming various scenes in and out of the water. At one point she hurt her neck while purposely falling off the surfboard. The aging beauty then changed into a skimpy red bikini for a sunset shoot."

The movie "Flirting with 40" is about a woman (Heather) who goes on a vacation to Hawaii after a divorce. She takes surfing lessons and falls in love with the instructor - with romance and comedy ensuing.

Alongside Heather, Robert Buckley is playing the part of instructor. Vanessa Williams also has a role in the film based on a novel by Jane Porter.
