Yovanna Ventura celebrated Justin Bieber’s 21st birthday with him on a Caribbean island this weekend. Hollywood Life reports that the two–who dated before his days of dating Selena Gomez–are back together again.

Do you suppose Selena Gomez minds that Justin Bieber is back together with his old flame?

“While she doesn’t dislike Yovanna, Selena was well aware that the model held a torch for Justin,” a source shared. “Especially after Selena and Justin tried to make a go of their relationship towards the tail-end of last year.”

Yovanna Ventura and Justin Bieber cuddled up with her leg wrapped around his shirtless body on Justin’s 21st birthday. Yovanna shared the photo on her Instagram account.

“Happy birthday,” Yovanna captioned the sexy shot.

It has been several months since Yovanna Ventura and Justin Bieber were pictured together. It was back in July that she flew in to New York Fashion Week–and he was still dating Selena Gomez then.

Some sources say Justin Bieber is dating Hailey Baldwin, while others say the two are just friends. So what do you suppose the case is with Yovanna Ventura? Are the two really back together again or were they simply hooking up for Justin’s 21st birthday?
