Selena Gomez makes her relationship with Justin Bieber Insta-official; wishes him happy birthday

Justin Bieber and Selena Gomez are giving love another try and this time, it looks like Jelena is here to stay. 

The couple was in an on-and-off relationship from 2010-2014 and it was only last year, after Selena's kidney transplant surgery that the ex-flames reunited. Since then, Jelena can't take their hands off of each other and we are definitely not complaining. 

From Valentine's Day to Selena being Justin's plus one at his dad Jeremy Bieber's wedding, this pair is going strong. 

Yesterday, Justin celebrated his 24th birthday and while the couple has kept mum about their relationship (their PDA speaks for itself), Selena took to Instagram to wish her man in a special way.

Sharing a picture of herself with a polaroid of Justin stuck to her forehead, Selena wished Justin with the cutest caption.

March 1, 1994 someone I know that happens to be super cool was born. Boom.

Selena's caption reads as, "March 1, 1994 someone I know that happens to be super cool was born. Boom."

Selena's grin says it all, doesn't it!

We're loving Jelena 2.0! How about you guys?

Meanwhile, Selena is going all out to make her boyfriend feel special on his big day, according to a leading US-based entertainment website. An insider revealed to the website, "She has been busy plotting and planning with Justin’s friends to surprise him with a party full of those closest to him."

Selena is in touch with Justin's family and manager Scooter Braun to throw a birthday party for Justin that he will never forget.

Going the romantic route, the insider added, "After all the gifts have been opened, and the party ends, Selena is looking forward to some private, intimate time for just the two of them. She is doing her best to make Justin’s birthday as romantic and unforgettable as possible."
