Is Justin Bieber upset about Hailey Baldwin possibly moving on from their up and down romance?

According to a new report, Bieber contacted his ex-girlfriend after hearing about her and Drake and during their chat, the 22-year-old singer reportedly informed Baldwin to steer clear of the "player."

“Justin is telling Hailey that Drake is a player and she should watch herself around him at all costs,” a source close to Bieber told Hollywood Life on Wednesday. “She is laughing off Justin‘s talk and considering it jealousy and that he it is a matter of the pot calling the kettle black.”

Since Bieber and Baldwin began spending time together in December of last year, at which point they enjoyed a romantic vacation together, Bieber has also been spotted with several other women, including Jessica Serfaty, Sarah Jeffrey, Selena Gomez, Kourtney Kardashian, Nicola Peltz and, most recently, Rita Ora.

Throughout Bieber's time with other women, Baldwin has continuously taken him back and less than a month ago, the on-and-off couple was seen in New York City together traveling from a club to her apartment.

Weeks later, after Bieber took Nicola Peltz out in a dinner date to a fancy restaurant in Beverly Hills, Baldwin stepped out with Drake.

“Drake and Hailey were most certainly on a date Tuesday night. They started the night at Ysabel restaurant on Fairfax and they finished the night back at his place,” an insider dished to Hollywood Life. “After dinner, they went to Nice Guy for a bit before going back to his place. He was a gentleman the whole time, opening doors for Hailey and things like that."

“[Hailey] looked really hot [and was] putting out the vibes like she wanted to look good for him — and it was working," the outlet continued. "The pair looked like they had good chemistry together and were into each other. Drake was for sure feeling her.”
