Gonna party like it's 3012! Justin Bieber turned the big 2-1 on Sunday, March 1, and — like any true "Heartbreaker" — celebrated with lots of lovely ladies around him.

According to TMZ, the "All That Matters" singer feted his 21st birthday on a private island near Grenada on Saturday, Feb. 28. A video posted to Twitter shows him dancing shirtless to 50 Cent's "In Da Club," as fellow revelers wave sparklers in the air around him.

One of those revelers was pal Hailey Baldwin, the 18-year-old model and daughter of actor Stephen Baldwin. She shared a photo from the bash via Instagram, of herself hugging Bieber from behind as he stares dazedly into the camera. (The two have been spotted hanging out in recent months, but both deny they're more than friends.)

Rumored former hookup Yovanna Ventura also posted a picture from the party on Saturday. In the shot, she halfway straddles Bieber, one leg around his waist, as he pulls her close and grabs the underside of her thigh.

Happy birthday!! ????

"Happy birthday!!" she captioned the photo.

Bieber himself tweeted a couple of updates to fans in the hours leading up to his actual birthday. "Grateful to be alive!!! Love u!!! 21," he wrote. "I love everybody!"

Hours later, he shared a goal for the coming year. "Thanks for all the birthday love. Grateful for everything," he tweeted. "Let's be better this year. Thanks."
