Actors Glen Powell and Sydney Sweeney s playful banter at CinemaCon this week bodes well for their upcoming rom-com Anyone But You but it also fueled rumors that the two werent acting and that their apparent chemistry spurred Powells breakup with his ex Gigi Paris.

The two stars appeared to be Mondays main attraction at CinemaCon as Sweeney playfully cut Powell off mid-presentation and exclaimed, Oh, please, Top Gun, according to People .

I love when she calls me that, the Top Gun: Maverick star replied.

Anyway, as you could probably guess, this movies about two people that hate each other. Sydney plays a character [who is] a real nightmare, Powell added before Sweeney cut in to say his character was a real asshole, People reported.

Speculation is running rampant on social media that the actors became romantically involved while they were filming in Australia, which began in March and only recently wrapped. A source told Page Six that Paris and Powell broke up in early April but ET cited a source who said that Sweeney is still engaged to Jonathan Davino.
