Sydney Sweeney was all smiles at the NASCAR Cup Championship at Phoenix Raceway, despite her tense reunion with her ex-fiancé, Jonathan Davino , just hours prior .

The “Christy” star wore tight black leather shorts, a crop top, an oversized white racing jacket with a red stripe and red knee-high boots on Sunday. She styled her new blond bob with the ends flipped out and wore clear sunglasses.

Sweeney addressed the crowd and held a checkered racing flag at the event in Avondale.

She also smiled in a pic with WNBA star Sophie Cunningham, which the athlete posted on X.

“One of us forgot our tits at home,” Cunningham joked.

The night before, Sweeney was spotted getting into the passenger seat of a car being driven by Davino in Los Angeles, according to photos obtained by Page Six.
