Justin Bieber has been seen getting close to a former Playboy model.

The Confident hitmaker was seen dining and dancing with Moldovan beauty Xenia Deli in Los Angeles on Friday, following the wrap of his music video for What Do You Mean? in which he recruited her to star.

Fans watched on as he serenaded her on a piano, joking to the growing crowd: "I'll be here all weekend."

The pair also seemed to hold hands at one point, according to The Sun newspaper.

Deli, who has modelled for Playboy and Victoria's Secret, also posted an Instagram snap about her rumoured beau while holding a sign referencing the pop star's latest music video.

Meanwhile, the 21-year-old star previously revealed he was focusing on family rather than relationships.

He said last month: "[I have] no girlfriend at the moment, no. I'm single. My love? My love today is my little brother. He's staying with me for the next week. So he's my love right now."

And Bieber also revealed he enjoys cooking for breakfast for his girlfriends.

He shared: "I cook breakfast, and that's pretty much it. For myself or if I have a girl. I made breakfast for my little brother the other day, some eggs, pancakes, and bacon. Simple."

In the past, Bieber enjoyed an on/off relationship with Selena Gomez and has been romantically linked to the likes of Hailey Baldwin and Kendall Jenner in the past.
