Cheeky: Demi Lovato strips of

 

The Confident singer has been filming the Victoria’s Secret Swim Special with a host of VS beauties on the Caribbean Island as well as enjoying some downtime with her boyfriend Wilmer Valderrama.
And when they haven’t been packing on the PDA beach side, the star has also been playfully stripping off.
The latest pictures show her wading into the sea in a flattering plunging black costume, before she peels it off when Wilmer arrives.
The star then held it up out of the water to show him as he looked down from the cliffs above.

 

The singer proudly held it up to show her boyfrien.

 

 

Demi joined the VS beauties on their latest campaign

 

Other snaps show the star and her handsome other half recreating the Dirty Dancing lift made famous by Patrick Swayze and Jennifer Grey.
The loved-up pair were also joined by Nick and Joe Jonas who shared plenty of social media images from their stay.
In one snap of Demi, Wilmer and Nick, the Jonas brother poked fun at always being the third wheel.
Changing the lyrics of The Weeknd's song, he shared: "I'm always third wheel when I'm with you.. But I love it... Yeah I love it ohh."
