A number of famous faces attended Selena Gomez's 21st birthday bash on Saturday night, but all eyes are on one - her ex Justin Bieber.
Though Selena has repeatedly confirmed their breakup, sources say the two appeared more than friends at her gypsy-themed celebration at the Revolve Beach House in Malibu. A source tells People that Justin arrived fashionably late at midnight with his pal Jaden Smith. Although he wasn't dressed up in costume, the 19-year-old was reportedly carrying a single red rose when he entered.
Another source tells "E! News" that Selena and Justin ended up leaving the party together at around 2 a.m. in the teen star's distinctive cheetah print Audi. Selena's new album, which includes a breakup song about Justin called "Love Will Remember," is expected to debut at number one on Billboard charts this week.
