Pop star Sabrina Carpenter faces cheating allegations after making a surprise appearance for fans.

At the premiere of her Netflix Christmas special on Thursday, Sabrina Carpenter surprised fans with rumors circulating that Barry Keoghan had cheated on her.

Despite rumors that her relationship with Keoghan ended due to infidelity, the carpenter was in high spirits while promoting "A Nonsense Christmas."

TikTok influencer Breckie Hill, with 4.3 million followers, contributed to the infidelity rumors by sharing a video on the platform.

On the final night of her largest tour in LA, she was seen getting intimate with a blonde, semi-famous LA-based influencer who is well-known for her TikTok presence at San Vincente Bungalows.

"Out of curiosity, I searched around and discovered that he and his pop star girlfriend ended their relationship abruptly just days before her final performances in LA. It appears that she discovered he had been secretly communicating with an influencer for months in an inappropriate manner."

Both Carpenter and Keoghan were contacted by Planet Chronicle Digital for comment.

An insider confirmed that the two are taking a break after first sparking romance rumors in December 2023.

According to People magazine, both individuals are young and career-oriented, which led them to take a break.

After landing a role in "Dunkirk," Keoghan's acting career took off. He has since starred in "Batman," "Eternals," and the viral film "Saltburn."

The "Girl Meets World" star's latest album, "Short N' Sweet," has garnered significant success.

The female artist, who was previously an actress, achieved the feat of being the first woman to have three songs in the top 10 of the Billboard 100 for five consecutive weeks.

Since their release, "Espresso," "Please Please Please," and "Taste" have been popular.

The "Short N' Sweet" tour of Carpenter commenced in Columbus, Ohio, on Sept. 23 and concluded the U.S. leg in November with three nights in Los Angeles.

She is currently on a winter break while preparing for the international leg of the tour, which will begin with Carpenter taking the stage on March 3 in Ireland and end on April 4 in Stockholm.

The pop star has accepted criticism for her choice of lingerie outfits during her tour.

"The "Taste" singer stated to Time magazine that mothers with strong opinions on clothing will still occasionally attend the show, to which he responds by saying, "Don't come to the show," and that's acceptable."

""Unfortunately, the scariest thing in the world is getting up on a stage in front of many people and performing as if it's nothing. If dressing in a way that makes you feel comfortable helps you do that, then you should do it," she said."
