On Instagram, Bieber posted a photo of Gomez from this year's Vanity Fair Oscar party, looking beautiful in a gold floor-length Emilio Pucci halter dress.

He captioned the image: "Most elegant princess in the world."

MTV points out that perhaps the singer chose to post an image from the Vanity Fair party because it was at that same party in 2011 that the two went public with their relationship.

Selena, meanwhile, posted a photo of herself at the party embracing her friend Vanessa Hudgens, which she captioned: "my only, official party buddy for life ;)."

Bieber, who turned 20 this past Saturday, showed gratitude for all his birthday greetings, tweeting, "Thanks to everyone for all the birthday wishes. Means a lot. Blessed and hoping we can continue to change the world together. Thanks."
