They are a perfect “combination”.

Rebel Wilson was seen delivering some serious PDA with girlfriend Ramona Agruma at the US Open.

The “Senior Year” actress and her blonde babe locked lips while sitting in the stands at Arthur Ashe Stadium on the grounds of the Billie Jean King National Tennis Center in Queens.

The pair looked very much in love as they watched Serena Williams defeat Danka Kovinic in a 6-3, 6-3 first-round victory in the tennis champion’s final match before her retirement.

At one point, Wilson was seen sweetly resting her cheek on Agruma’s shoulder as they both flashed bright smiles.

The duo were seen giggling as they chatted and were photographed enthusiastically cheering on the tennis champions from their seats.

The “Pitch Perfect” star looked chic in a pink dress and matching blazer for the occasion. She accessorized with a black Hermés bag.

Meanwhile, her fashion designer girlfriend wore a black dress with a white lace collar and a Chanel crossbody purse. She slicked her hair back into a sleek bun.

Wilson and the Lemon Ve Limon founder have enjoyed a number of adventures together since going public with their relationship.

Wilson revealed that she was dating Agruma in June while simultaneously coming out as a member of the LGBTQIA+ community.

“I thought I was searching for a Disney Prince… but maybe what I really needed all this time was a Disney Princess #loveislove,” Wilson captioned a selfie on Instagram with her new flame at the time.
