The couple were seen smiling and laughing with one another, choosing to shyly hide behind Ashton's baseball cap to share a tender kiss when they were targeted by The Staples Centre's 'kisscam'.
Stylish actress Mila was dressed casually in black heeled ankle boots, navy leggings with lighter blue panelling and a grey top under a similarly hued blazer.
Embarrassed at being singled out of the crowd, Mila held her hand over her mouth, showing off nails which were painted royal blue and orange.
Ashton and Mila were not the only famous faces in the crowd watching the Utah Jazz take on the LA Lakers.
Newlyweds Kaley Cuoco and Ryan Sweeting happily sat together for the game, with The Big Bang Theory actress sporting a branded cap to support the home team.
Kaley, who tied the knot with Ryan on New Year's Eve, gave a close up of her new glittering wedding rings.
Like Mila, Kaley had also given special attention to her nails and added gemstones to the nail on her newly adorned ting finger so that it stood out amid her elegant manicure.
