AceShowbiz - Sabrina Carpenter shows the world how she copes with a heartbreak following her split from Barry Keoghan. Not letting the breakup and cheating allegation against her ex-boyfriend dampen her spirits, the actress/singer appears to be joyful in her first public outing since the news broke.

On Thursday, December 5, the 25-year-old stepped out for the New York City screening of her "A Nonsense Christmas" Netflix special. Making her way into NYC's Paris Theater, she flashed a radiant smile while greeting and waving her hands to her fans waiting outside the building.

For the screening, Sabrina turned heads in a bold mini dress with black-and-white fur detailing and matching furry black-and-white heels. She showed off her toned legs in the flirty look while her light blonde tresses cascaded down her back in loose waves. She added dark red lipstick to match the holiday spirits while accessorizing with some silver rings and a pair of sparkly earrings.

Sabrina's Netflix special is set to premiere on the platform on Friday, December 6. The holiday special features guest appearances from stars such as Chappell Roan, Shania Twain and Cara Delevingne.

Sabrina's NYC outing comes on the heels of reports that she had called it quits with Barry after dating for one year. "They are both young and career-focused, so they've decided to take a break," a source told PEOPLE on December 3.

Around the same time, DeuxMoi posted a blind item that alleged the "Espresso" singer decided to end their relationship due to his infidelity. "When Sabrina was wrapping up her last show dates in California on her Short N Sweet Tour. Instead of attending the show Barry was seen out in public with the influencer," a source told the blogger.

"It appears that this A-list singer who's having her breakout year and her foreign actor boyfriend are done for good," the blind item posted on Monday, December 2 read. "On the closing night of her biggest tour to date in LA, he was busy getting very cozy at San Vicente Bungalows with a blonde, semi-famous, LA based influencer (who's particularly big on tiktok)."

The source added, "I snooped around a bit out of curiosity and apparently he and his popstar girlfriend called it quits very suddenly less than a week before her final shows in LA after she found out he had been chatting with said influencer behind her back for months in a not-innocent-at-all way..."

They added, "He had messed up before and she had forgiven him but nothing as serious and infidelity is where she draws the line." According to the blind item, "The popstar wants to keep the situation under wraps at least until January because her next single is a steamy song inspired by their relationship and she's already filmed a music video with very obvious references to him..." However, "the influencer is running her mouth a lot and he isn't doing much to stop her..."

While Sabrina and Barry have not addressed their breakup, Breckie Hill has fueled the cheating allegation. The social media personality, who has over 6 million followers across TikTok and Instagram, has reposted a clip that seemingly hinted at an affair between herself and the Irish actor.
