Have Justin Bieber and Hailey Baldwin taken their friendship to the next level?

The 20-year-old pop star and 18-year-old model, daughter of actor Stephen Baldwin, have sparked dating rumors for weeks. They have previously said they're friends. On Friday, the day after Christmas, they were seen out alone at the Mr. Chow Chinese restaurant in New York. As they left the posh eatery, Bieber smiled and held what appeared to be a plate against his face.

Hailey met Bieber at his home and they were then driven by a chauffeur to the restaurant. The two looked like a couple, an eyewitness said, adding that Hailey brought a gift for the singer. The two spent more than an hour at the restaurant and then headed to a movie theater, where they watched The Gambler, a crime thriller starringark Wahlberg.

The pair later returned to Bieber's residence. On Saturday morning, the two were seen at a diner in New Jersey.

On Saturday afternoon, Hailey took to Twitter to clarify where she spent the night.

"Glad I got such a good night sleep last night, at MY own home, alone," she said.

Hailey and Bieber had previously dismissed relationship rumors, despite being spotted during the last few weeks having lunch in Beverly Hills, shopping at Target, sitting courtside at a Los Angeles Clippers game and playing arcade games together. In November, he joined her at her birthday party.
