Britney Spears has always said that the beach is her happy place, especially when it comes to her beloved yoga practice. While autumn is officially here on the calendar, in L.A. it is still hot and sunny. The singer showed off three Instagram photos on Sept. 23 of her bikini beach body, wearing a sexy red two-piece string number. She used her core muscles to hold her legs high in the air above her body, as the ocean’s waves crashed ashore in the background.
