Justin Bieber seems to still be pining for ex-girlfriend Selena Gomez, E! reports. The singer, who turned 20 on Saturday, shared a photo yesterday on Instagram of Gomez at the Vanity Fair Oscars after-party in West Hollywood, captioning it: "Most elegant princess in the world." Gomez was shown posing on the red carpet looking stunning in an Emilio Pucci dress. Gomez hasn't responded. But she did post an Instagram photo of herself and pal Vanessa Hudgens cuddling on a sofa at the party, calling her "my only, official party buddy for life."
