The pair were caught on camera at the game in L.A. on Saturday
The newly engaged couple were attending an L.A. Clippers game on Saturday when they ended up on the Kiss Cam.
While Kunis, 30, put her hand over her mouth and feigned shyness, her fiancé was up for the challenge.
Quickly and deliberately turning his baseball cap around for better access, Kutcher, 36, grabbed Kunis and brought her in close for a smooch (while Barry White’s “Can’t Get Enough of Your Love” played) before pointing to the camera in triumph.
Kunis, who’s set to guest star on Two and a Half Men with Kutcher, laughed and covered her face in embarrassment.
