Wouldn't you love to hear a Selena Gomez and Britney Spears duet?! It could happen! Selena Gomez and her "Spring Breakers" co-stars sang a little Britney karaoke during a Q&A at SXSW. Britney heard about this and reached out to the former Disney star via Twitter: "Awww @selenagomez can duet with me anytime. PS- I heard @springbreakers is AAA_MAZING! Can't wait to see it!" Cross your fingers that the collaboration actually happens!! See the video of Gomez singing some "Baby One More Time" below!!
