Selena Gomez ended her big 21st birthday party last night by leaving with ex-boyfriend Justin Bieber.

At the beginning of the night, Bieber rolled up to The Revolve Beach House in Malibu, where Gomez hosted her party, in his leopard print Audi R8 sports car, bringing with him a single rose for the birthday girl, according to People.

Besides Bieber, other stars at Gomez’s gypsy themed party included Nina Dobrev and Julianne Hough, who looked like they were having a blast in Hough’s Instagram photo, captioned “Gypsy girls.” The party goers dressed up according to the theme, donning crop tops, skirts, and head scarves.

Gomez turned 21 this past Monday. The “Come & Get It” singer's Gypsy party culminated a week-long celebration. On the night of her actual birthday, Gomez went out to dinner with friends and family.The next day, she released her new album, Stars Dance.

At the end of her bash last night, Gomez and Bieber left the other partiers arm-in-arm. Bieber even abandoned his Audi to leave with Gomez in her car, according to KpopStarz. Does this mean the pair are back together?
