Justin Bieber may be a huge star but he celebrated his 21st birthday like any other youngster able to drink legally for the first time, minus the whole private island thing.

The Biebs celebrated the big 2-1 on a private Caribbean island near Granada and posted a video dancing to birthday staple, 50 Cent’s “In Da Club,” while chugging champagne straight from the bottle. Sounds a lot like OK!’s type of party…

Of course, his leading lady—who insists they are still just friends—Hailey Baldwin was in attendance to celebrated her BFF’s big night but she wasn’t the only babe around.

Biebs’ former girlfriend Yovanna Ventura was also in attendance and posed in a sexy snapshot with the 21-year-old grabbing her booty!

Justin was rumored to be dating Yovanna some time ago, and it looks like the two kept close over the past few months.

Aside from the video showing Justin dancing around a pool shirtless, he kept his social media pages pretty quiet but later thanked fans for the bday wishes.

“Grateful to be alive!!! Love u!!! 21,” he wrote a day before his birthday, after reportedly celebrating for a few days. "Thanks for all the birthday love. Grateful for everything," he wrote in another tweet. "Let's be better this year. Thanks."

He also posted this photo with his dad, Jeremy, writing: “Look at pops double chin.” Guess his dad was also a guest for the wild weekend!
