Bieber tweets telling snapshot

Are Justin Bieber and Selena Gomez together again?

They look lovey-dovey in a quickly-pulled Instagram photo Justin posted online, with Selena holding her hair back and leaning in close to Justin.

Bieber deleted the photo immediately after he posted it.

The former couple reunited backstage at Justin's concert in Oslo, Norway, last week - with reports the two were holding hands and kissing.
