Who hired HER? Jennifer Lopez covers up her bikini as underwear models strut around on video set

It's not like Jennifer Lopez to be shy about showing off her curves.

But with beautiful underwear models strutting around the set of her new video no wonder she felt a little shy.

The singer kept her bikini under wraps in a kaftan on the beach as she filmed with Pitbull in Fort Lauderdale, Florida on Saturday.

But while the mother-of-two had an admiring glance for one of the scantily clad male models, it wouldn't be surprising if she wasn't pleased with the casting director.

For strutting around on set were a host of beautiful underwear models, including America's Next Top model beauty Eva Marcille.

Eva clearly isn’t one to feel body conscious.In fact in her barely there ensemble, which showed off her incredible legs, she risked upstaging the star of the show herself who would have to pull something particularly impressive out of the bag to once again take centre stage.

The one time winner of America’s Next Top Model, 28, proved once again why she has enjoyed a successful career after the reality show as she displayed her fabulous physique.

Wearing a pair of big knickers with a black bikini top, her very toned stomach was proudly on display and a tattoo could be seen on the lower section.

It was however her legs which stole the show, looking incredibly toned and very long heightened by a pair of platform black heels.

Protecting her modesty slightly she wrapped a white dressing gown around her shoulders, while she carried a bottle of water in her hands.
