The fun-loving couple was all smiles as they sat courtside—and even locked lips for the Kiss-Cam!—at the Clippers game on Saturday night.
The 30-year-old starlet wore a gray long-sleeve top and subtly flashed her beautiful engagement ring as she adjusted her fiancé's Chicago Bears cap.
The lovebirds are pros at this point at getting picked up for the Kiss-Cam and they appeared on the jumbotron during a timeout, a source reveals to E! News. Kunis and Kutcher "made out for a second" and the crowd cheered during the impromptu PDA moment.
"It was so cute," the source added.
The Clippers twitter handle added an adorable collage-style snapshot of the engaged pair, sans smooch. Kunis appears in disbelief as she covers her mouth with her hand, while Kutcher looks a bit more relaxed in one photo as they prepare to pucker up.
The Jupiter Ascending actress flashes a big grin and the Two and a Half Men star points to the camera in the other photograph, presumably post kiss.
The A-listers were good luck for the Clippers because they beat the Detroit Pistons, 112-103.
Before attending the basketball game, Kunis and Kutcher were spotted grabbing a casual bite to eat.
The That '70s Show co-stars held hands as they made their way to Sweet Butter Kitchen in Studio City for a lunch date.
