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. 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."
