Hailey Baldwin shares birthday photo with Justin Bieber

Hailey Baldwin took to Instagram to share a birthday photo with Justin Bieber on Sunday.
The 18-year-old model posted a picture of herself embracing the singer, and captioned the snapshot, "21." Bieber turned 21 years old over the weekend, and celebrated the milestone with Baldwin and other friends on a private Caribbean island.
Yovanna Ventura also shared a photo of herself with Bieber at the bash. The 19-year-old model posted a picture of herself wrapping her leg around the pop star, and captioned the snapshot, "Happy birthday!!"
Baldwin and Ventura have both been romantically linked to Bieber in tabloids, a rumor the former last denied in February. Ventura has been spotted with the singer in Venice Beach and Las Vegas, but not publicly addressed dating reports.
Bieber himself took to Twitter to thank his friends and fans for their well-wishes, writing, "Thanks for all the birthday love. Grateful for everything. Let's be better this year. Thanks." The singer will be roasted on a Comedy Central special hosted by comedian Kevin Hart on March 14.
