The contestant, 24, who entered the villa on Sunday stares straight at the camera with her hair in curls.
Another shot from the same shoot shows her in black lingerie.
The re-surfacing of the snaps comes a day after it was revealed Meghan used to work as a stripper.
In last night's episode the model from Essex who has shared some of her sauciest pics with The Sun Online made the confession during a chat with Dr Alex George.

Megan also used to sell X-rated pictures of herself online.
The doctor – who has the hots for Megan – said he thought it was liberating to hear her talking openly about what she used to do.
Her previous role means she is seriously body confident and in another set of sexy snaps, she poses in nothing but skimpy black knickers.
Another picture shows her pouting and playing with her hair in a white lace lingerie set.
Before going into the villa, Megan insisted she'd be a hit with the men in the show as she's so different to the other girls.
She said: "I think the first obvious thing [that makes me stand out] is my look.
"The other girls are all very toned and I'm quite curvy. I've got big boobs and a big bum. I'm very real.
"I'm more chilled than the other girls. In that way I'm more like a guy, very laid back."
She entered the house on Sunday along with two new boys, Josh Denzel and Charlie Frederick.
