Justin Bieber-Selena Gomez Dating Again? Beebs Flies In With Rose For Selena's Birthday, Jelena Sneak Out, Go Home Together After Party

Selena Gomez and Justin Bieber may be back together-the two apparently went home together after Gomez's birthday bash. Bieber brought Gomez a rose...and it may have been enough to woo her.

It would be a happy birthday indeed for Selena if she and Beebs are dating again. The split is off, many believe. She just turned 21, and her party may have had a happy ending.

"Justin flew in specifically for the party on a day off from his tour," a source said.

Bieber showed up after Gomez's parents had just left-perhaps for a reason. After all, he may just be, uh, Biblically corrupting their daughter.

Bieber rolled up to the party on Saturday night in his leopard print Audi sports car with some pals. He was holding a single red rose.

The star-studded party took place at The Revolve Beach House in Malibu. It was a Mediterranean themed party with hookahs, belly dancers, Middle Eastern food, and a cake shaped like an elephant on a pillow with a giant "21" on top.

Other celebs in attendance included Julianne Hough, Nina Dobrev, Derek Hough, Ashley Benson and Jaden Smith.

Beebs looked dapper in black jeans, a crisp white T layered with a green jacket, and white high-top sneakers.

Jaden Smith allegedly helped sneak Gomez and Bieber out of the house under a blanket and an umbrella...and they were holding hands.

The two jumped into a car and sped off into the night together.

Apparently, Gomez's parents had left when Bieber showed up...just in the nick of time. After all, they might not want anyone corrupting their precious daughter.

Justin and Selena left around 2 am arm-in-arm. Do you think they're back together? Sound off in the comments below!
