Selena Gomez was glammed up at the 2013 Teen Choice Awards in L.A. on Sunday, but she stripped down at the pool as she celebrated her TCA wins.

The former Disney Channel star was a big winner at yesterday's award show, bagging three trophies for herself. Selena wore a green, double-slit Cushnie et Ochs dress as she accepted her Choice Breakup Song award on stage for her new single "Come and Get It." She also won Choice Hottie, Female and Choice Music Star, Female.

"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 told her fans and the audience at the awards show. "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."

However, after the show at the Gibson Amphitheatre, Selena chose to relax and let loose with some of her homegirls in a pool.

The 21-year-old singer posted a few images on her Instagram account, sharing how she spent her time at the post-TCA party. She first posted an image of her friend with the caption "She's just so." Gomez then followed it up with a few more images of her and her girl pals in bikinis having fun in the pool. One photo had the caption "Bye LA" which could refer to the TCA venue in Los Angeles. One image also noted that her partying friends were Brazilians.

According to Hollywood Life, the retro bikini worn by the actress-slash-singer can be found in Topshop.

"This one in particular, which we're sure was posted by Selena to toy with Justin's emotions, is a tropical-print bikini, which you can find at Topshop for just $68!"

After the TCAs and her pool party, Selena is set to kick-off her "Stars Dance Tour" in Canada Aug. 14.
