Britney Spears is all about showing off her amazing body -- and this weekend was no different!

On Sunday, the 34-year-old flaunted her toned body in a flower patterned bralette and tiny pink shorts while dancing around to to Meghan Trainor's hit song "Me Too."

The mom of two captioned the video, "It's been a while since I've cut loose 😂😜." She certainly did cut loose -- and we love it!

The singer highlighted her taut tum, sculpted legs and her bottom while shaking it to the pop song. Britbrit was getting super into it -- she even flashed her undies to the world! Oh and those extensions -- they're ridiculous!

You can see more of the "Gimme More" singer through May 2017 at her Las Vegas residency, Britney: Piece Of Me show at The Axis auditorium inside Planet Hollywood Resort & Casino in Las Vegas.
