The actress treated her 4.7million Instagram followers to a behind the scenes snap of her clad only in a white lace lingerie while on a recent photoshoot.
The stunning 31-year-old is showing off her enviably slim frame in the sexy, sheer look as she poses seductively in front of a mirror.
She’s wearing her brunette locks in tousled waves and is sporting a number of necklaces and rings.
Alongside the picture, mum-of-three Megan told her fans she was working on another campaign with lingerie brand Frederick’s of Hollywood.
“At it again. Sneak peek, coming soon- just in time for festival season,” she wrote.
