Britney Spears sings about how to "look hot in a bikini" in "Work Bitch" ... and now she's actually doing it!
The singer just shared three awesome photos from her family vacation, showing her in two different bikinis while enjoying some downtime with boyfriend David Lucado and her adorable sons, Sean Preston and Jayden James.
In one pic, Brit Brit is seen wearing a blue bikini, showing off her incredibly fit (and bejeweled) stomach inside her hotel room.
In another, the entire crew makes some seriously silly faces while posing for the camera. We love her kids -- they're so goofy, just like their mama!
The group traveled to Hawaii after attending Jamie Lynn Spears' wedding in New Orleans earlier this month.
