Hailey Baldwin allegedly pressured Justin Bieber to commit to her. The 19-year-old model apparently demanded that the Boyfriend singer make the couple's relationship official.

"She demanded he stop stringing her along," a source apparently told Us Weekly. "She said he would lose her if he didn't man up and show he was serious about her."

"Justin has never had a woman act like that before," the insider added. "He couldn't say no. So he's been seeing her again and is with her all the time."

Alec Baldwin's niece has always insisted that the pair are just friends. Hailey told E! News in February 2015: "We're just friends. I've known him for a very long time, since I was about 13. But any male in his place, any girl that's around him they automatically assume. That's the world we live in. I'm just trying to be there for him and support him as a friend."

Meanwhile, the Baby singer had previously revealed that he wants to settle down. When asked by The Late Late Show host James Corden where he sees himself in 10 years, the 21-year-old singer replied: "I want to be completely secure in myself and have a family."

In an earlier interview with Z100â€ēs Elvis Duran, Selena Gomez's former boyfriend revealed he is careful in whom he puts his faith. Bieber has not had the easiest of times in the past years. He had to face criticism over a series of scandals, including fights with the paparazzi and allegations of assault.

"Trusting people is hard, especially for me. I've trusted people who I probably shouldn't have trusted before and they've hurt my heart," he said. "I'm a pretty sensitive guy, so I'll lay it all on the line, and they'll kind of pull it. So now I'm figuring out there's certain people I can't do that with."

"Here's what I'll tell the people: Don't let someone who ruined your trust ruin that next person's chance to gain that trust. I think I let that affect me and change the way I looked at people for a while," he added.

New Years ?
