All you gossip-mongers out there who have been wanting to know what exactly happened inside Selena Gomez's 21st birthday bash, here is the big dope.

If you thought that Selena's birthday won't pass by without Bieber making a grand romantic gesture, full points for our raging instincts.

Bieber left the crowd jaws dropped as he turned up for Selena's birthday celebration. Initially, young Justin got everyone wondering if he would make up to her birthday pasty as he gave her a cold shoulder for most of her birthday week. What's more, he didn't even wish her on her birthday.

 

So when he walked into her huge birthday bash held on the Revolve Beach House in Malibu, Calif., on July 27, it surely grabbed all eyeballs, more so headlines.

Justin walked in at the party, dressed in classic letterman varsity jacket and holding a rose in his hand, just after midnight. He drove in in his classic leopard print car with buddy Jaden Smith. Though he was with a group of guy friends, Justin soon made his way to meet Selena.

 

Buzz is that the couple was all over each other all night. He pampered her with some heavy PDA and even left together after the party.

Earlier, on July 21, Gomes stated that she wasn't seeing Bieber.
