Selena Gomez and Justin Bieber may have recently celebrated the New Year holiday together in Cabo San Lucus, Mexico.

However, according to a new report, the couple may not be on the best of terms. Gomez and Bieber flew back to Los Angeles from Mexico earlier this month on a private jet together but when they made their way off the plane, they were said to be arguing.

On Jan. 2, The Blast claimed that after a romantic trip to Mexico, Gomez and Bieber left the airport in Van Nuys separately without so much as a hug or a kiss. Could a breakup be looming? While nothing has been confirmed quite yet, the recently rekindled couple was recently said to be in couples therapy.

As TMZ explained last month, Gomez and Bieber reportedly came to blows after Gomez reportedly learned that Bieber had been in contact with his former girlfriend, Hailey Baldwin. According to the report, sources at the Hillsong Church claimed Bieber had reached out to Baldwin in an effort to make amends following a sour breakup years prior.

Then, because he has taken on an "open and honest" approach to life, he informed Gomez about their conversation. Although Bieber was thinking that honesty would be the best policy, he reportedly found himself in hot water with Gomez who wasn't happy to hear that he had been in touch with an ex-girlfriend.

Gomez and Bieber rekindled their on-again, off-again romance at the end of October following Gomez's 10-month relationship with The Weeknd. Since then, they've been faced with a number of rumors in the months since going public, including breakup rumors and rumors of a future wedding. They've also been dealing with ongoing rumors regarding Gomez's family's alleged disapproval of their relationship.

At the end of last month, a source spoke to Hollywood Life about Gomez's family's reported thoughts on her romance with Bieber. The insider claimed that Gomez is understanding of her mother's stance but hopes she will soon see that her boyfriend is a changed man.

“Selena gets why her mom has so many reservations about her seeing Justin again, but she just wishes Mandy would trust her judgement and give him a break," the insider said. "She’s upset, but totally not phased by her family’s disapproval though, if anything it makes her all the more determined to make it work out with Justin to prove them wrong."
