Heather Graham stuns in string bikini as she enjoys 'dream time' with boyfriend on Mexican beach

Heather Graham sizzled in a skimpy striped string bikini as she enjoyed some fun under the sun with her boyfriend Michele Civetta while vacationing in Tulum, Mexico.

The 56-year-old actress and the 49-year-old Italian filmmaker were spotted strolling down the beach after taking a dip in the ocean last Tuesday. 

Graham's Dandy Del Mar black and white two-piece featured a triangle top and tiny bottoms that tied at the hips. Civetta wore blue and orange striped swim trunks with a back pocket and a silver chain necklace.
