Even though Mila Kunis and hubby Ashton Kutcher are total #CoupleGoals, they hardly ever hit the red carpet together. Though they’re often spotted at sporting events, the duo likes to lay low, keeping their marriage mostly to themselves. But on Sunday, Dec. 3, the parents-of-two were flirtatious AF on the red carpet for the 2018 Breakthrough Prize at the NASA Ames Research Center. Watch the video below to see photos!

The couple tied the knot in a secret 2015 wedding ceremony, but they’ve been linked for years. They met while filming the hit sitcom That ‘70s Show back in 1998 when Mila was 14 and Ashton was 19. Though they’re clearly totally in love these days, the huge age gap made it admittedly awkward for the pair to play an on-screen couple.

While on The Howard Stern Show in June, Ashton opened up about the mother of his children. “I think I was her first kiss, like, on the show,” Ashton said. “It was really weird. I was like, ‘Isn’t this illegal?’ It was really awkward. She was 14! She was like my little sister. I wanted to make sure she was OK.”

These days, Ashton and Mila, 39 and 34 respectively, are parents to one-year-old Dimitri and three-year-old Wyatt. And though we’d love to see more little Ashtons and Milas running around, from what the Bad Moms star told People magazine back in November, they seem content with just two. “I will only have two. But I have heard [moving from] two to three is the hard [jump]. [It’s hard] when they outnumber you,” she said. “Right now, we’re fine. One hand, one hand. One eye, one eye. Two people, two kids.”
