It’s a battle of the bikinis!

Britney Spears, Demi Lovato, and Jennifer Lopez are all judges on hit reality singing competitions, and in addition to their musical ability, they all look fabulous in bikinis! While the 30-year-old “Toxic” singer and the 19-year-old “Skyscraper” songstress have only just begun their X Factor stint, Lopez, 42, is practically an American Idol vet after two seasons on the hit FOX show.

While millions trust their opinions on up and coming singers, the real question is — who looks best in a two piece?

While Demi and Britney are locked in for at least one season of X Factor alongside Simon Cowell and L.A. Reid, earning $15 million and $1 million paychecks respectively, the jury is still out on whether or not the “Dance Again” singer will return for her third season of Idol.
