Post-TCAs pool party? After getting all glammed-up to attend the 2013 Teen Choice Awards in Universal City, Calif on Sunday, Aug. 11, Selena Gomez let loose — and stripped down — after the show with some of her gal pals.

The 21-year-old singer posted several photos on Instagram Sunday night of herself and friends hanging out poolside in their bikinis. In one sexy shot, Gomez posed in a retro two-piece that showed off her cleavage and tiny waist. She captioned the shot, "Bye L.A." (The "Come & Get It" chart-topper is set to kick-off her Stars Dance Tour on Aug. 14 in Vancouver.)

The on-again, off-again girlfriend of Justin Bieber won three awards during the TCAs at the Gibson Amphitheatre: Choice Female Hottie, Choice Summer Female Artist and Choice Break-Up Song for "Come & Get It."

Taking the stage in a sexy double-slit green Cushnie et Ochs dress, Gomez looked gorgeous while accepting the surfboard award for Choice Break-Up Song. "Thank you guys so much. I think it's an encouraging song, so I'm glad that everyone is responding really well to it," she said. "I honestly appreciate you guys giving me the opportunity to do what I love every day. So this is your award, this isn't mine. Thank you so much."
