The couple, who have not officially confirmed their relationship despite numerous date sightings, were also seen holding hands while watching the game, reported Aceshowbiz.
The four of them watched the Dodgers take on the San Fransisco Giants from their exclusive seats at Lexus Dugout Club. Kunis, 29, donned a Dodger attire, while Kutcher, 34, wore a white-and-blue checkered shirt and baseball cap.
The on-screen couple of "That '70s Show", who just returned from their romantic vacation in Bali, have gradually gone public with their romance in the past few weeks.
Kutcher just split from his wife of seven years Demi Moore, while Kunis called it quits with actor Macaulay Culkin whom she had dated since 2002.
