The couple of nearly two years is engaged, a source confirms to Yahoo.

Kunis, 30, was spotted shopping with her mother at The Grove mall in Los Angeles on Thursday sporting a noticeable sparkler on her ring finger.

No further details were immediately available, but Mila made a point of showing off a ringless finger to paparazzi last week, when the duo traveled from LAX to New York.

The engagement caps a friendship that dates back to 1998, when they played dating teens Jackie and Kelso on TV’s "That '70s Show." He was 20 and she was just 15, so young that when a scene called for her to share a smooch with Kutcher, it was actually her first kiss ever. But it took years for their offscreen romance to bloom.

Kunis and 36-year-old Kutcher — whose divorce from Demi Moore was finalized in November 2013 — kept their romance on the down low at first, but eventually couldn't contain themselves any longer. Nowadays, the couple is lovey-dovey in public and seem to have a pretty cozy relationship. They've even started their own cute traditions.

"We have a thing called white T-shirt night and it's when you wear jeans and a white T-shirt and you go on a date," Kunis told Cosmopolitan this month. "Nothing fancy, it's just something that you love to do. And whether that's bowling or dinner or going to a cheese shop and have some wine or walking around. I think that's just the best thing to do — and sometimes it's just nice to stay home.
