Selena Gomez has a special birthday message for Justin Bieber

Selena Gomez and Justin Bieber are back together is the most open secret in the world.

For some reason, the couple hasn't made it official, but the reports about their happy times together come out every now and then to keep their fans updated.

A recent post by Selena Gomez on her Instagram account was both sweet and sort of officially announcing that the duo is together.

In honour of Justin Bieber's birthday, she posted a picture of herself with caption: "March 1, 1994 someone I know that happens to be super cool was born. Boom."

In the picture, Selena is smiling wide and happy with a polaroid image stuck on her forehead. The grainy picture could very well be of Justin Bieber.

The on again couple seems to be going strong. Last month the 'Wolves' singer accompanied Bieber for his father's wedding in Jamaica.

After splitting with her then-boyfriend The Weeknd, Selena Gomez reunited with Bieber last year in October.

Selena's mother, Mandy Teefey, however, is not happy with her daughter's decision to get back with her former ex.

On the other hand, the 'Sorry' singers mother Pattie Mallette is supporting the duo.
