Mila and Ashton were caught by the Staples Center's kiss cam much to the delight of fellow basketball game goers
Despite the Lakers losing the game, the duo seemed to be in high spirits, laughing and joking and posing for selfies with fans.
New mum Mila dressed down for the outing.
The 31-year-old sported brown ankle boots, jeans and a beige top while Ashton wore a similar outfit of blue jeans, a shirt and a grey jumper.
Mila and Ashton, who first met in 1998 when they co-starred in That '70s Show, became parents for the first time in September.
Iowa-born Ashton recently spoke about why the couple don't plan to have a nanny.
"We just want to know our kid," he said during an appearance on The Ellen Show. "We want to be the people that know what to do when the baby's crying to make the baby not cry anymore. We want to know when she makes a little face or something, we want to be emotionally in touch with her. And I think the only way to do that is by being the one who's there."
The 36-year-old also revealed what has surprised him most about fatherhood.
"You think you know how much you can love another person, and then you have a child and you realise you didn’t know. It's infinitely rewarding" he said.
