Sabrina Carpenter and Barry Keoghan's Relationship Is 'On and Off' (Exclusive Source)

Sabrina Carpenter and Barry Keoghan are keeping it casual.

Amid rumors of their split, a source exclusively tells PEOPLE that the relationship between Carpenter, 25, and Keoghan, 31, is “on and off.”

On Friday, Aug. 16, Keoghan also seemingly responded to the breakup rumors by liking the "Please Please Please" singer's flirty Instagram post, which showed her posing in baby blue lingerie.

PEOPLE reached out to reps for Carpenter and Keoghan for comment.

Meanwhile, Carpenter alluded to them having an undefined relationship in a June interview with Rolling Stone. When asked if she refers to the actor as her boyfriend, she replied, "How do I skirt around this question?"

She continued: "The [dating] pool is the pool, and when you meet people that feel authentic and are so brilliant and amazing in every way, that’s what you do. Obviously, I write songs about exactly how I feel, so I guess I can’t be so surprised that people are interested in who and what those songs are about. That’s something that comes with the territory.”

Carpenter and Keoghan first sparked romance rumors following a Los Angeles dinner date in December 2023 after they reportedly crossed paths during Paris Fashion Week two months prior. 

In February, the couple made their first public appearance at a Grammy Awards afterparty. Though they posed separately on the red carpet, they were seen cozying up together inside the event and party host W Magazine later shared a photo of them together.

The two confirmed their relationship a few days later when they were seen sharing a kiss after leaving Hotel Bel-Air in Los Angeles.

Carpenter showered him with praise when it came to his performance, describing him as "one of the best actors of this generation.”
