Surprisingly, E! News
reports that Selena Gomez and Justin Bieber were in the same room together for a lot of the night at Rihanna's party, but only "exchanged some words." Justin reportedly stuck next to Kendall and friends, while Selena -- who changed into a short black minidress -- stuck close to her gal pals, including her Spring Breakers
co-star Vanessa Hudgens. According to Us Weekly
, the two did tequila shots and danced up a storm throughout the night.
