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.”
