Justin Bieber and Nicola Peltz may be getting serious.

Weeks after the rumored new couple were spotted together in Toronto, Canada, a source claims they are enjoying sleepovers at the 22-year-old singer's Beverly Hills, Calif. home.

“The two have been chatting for a bit now,” an insider explained to Us Weekly on Wednesday. “He’s really into her.”

According to the report, BIeber and Peltz met at a party in Toronto and reconnected last month in Los Angeles, where they were seen enjoying a romantic dinner at Maestro's Steakhouse. Since then, they couple has been seen publicly just once, but as the insider revealed, they've been spending time together in private.

“Justin flew her to Toronto to show her around Canada,” said a source close to Bieber, who ended his relationship with 19-year-old model Hailey Baldwin earlier this year. “All his friends love her. They’re still going strong.”

Meanwhile, added the source, “Nicola likes Justin a lot.”

According to a separate report, via Hollywood Life, Bieber has been crushing on the 21-year-old Transformers actress ever since they met.

“Justin has known Nicola for a while and they met through mutual friends," their source explained. "Nicola is close friends with Gigi and she also knows Hailey. Justin met Nicola a while ago a couple of times while going out around LA, but they never hooked up cause the timing was never right. He has been crushing on Nicola since the first day he laid eyes on her. Justin has always wanted her. He has always wanted her. Justin was usually with Hailey or someone else and Nicola was usually with someone else too.”

“Justin and Nicola are definitely dating and it’s really heating up,” another insider told the outlet. “He flew her to Canada so she could watch his show and so they could enjoy a little vacation. Everyone really likes Nicola and thinks she’s good for Justin…and he’s totally infatuated with her!”
