Ashton Kutcher and Mila Kunis Pack on the PDA at Backstreet Boys Concert ArticlePure

Ashton Kutcher and Mila Kunis are so ‘90s! 

The pair were spotted packing on the PDA while attending a Backstreet Boys concert at the Sphere in Las Vegas on Saturday, Aug. 2. The band is currently performing a residency at the venue through Aug. 24.

Kutcher, 47, and Kunis, 41, danced and sang along to the band’s 1999 hit “I Want It That Way” from their third studio album, Millennium.

A video showed the couple singing the romantic lyrics to each other as they gestured dramatically with their hands. The Bad Moms actress, at one point, drew her husband closer, and he wrapped his arms around her waist. 

The two nearly kissed before pulling back and jumping along to the music.

“They stole the show on this one with a little fun. They were both gracious to the crowd and fans around them,” Michael Shawn McCabe, who captured the video, wrote in the caption.

Making their outing even cuter, Kutcher and Kunis wore coordinating outfits to the concert consisting of white shirts and navy blue bottoms.

The couple first met as costars on That ’70s Show, where they played on-screen couple Jackie Burkhart and Michael Kelso. The show aired from 1998 to 2006. They began dating in real life in 2012 and married a few years later in 2015.

They now share two kids, daughter Wyatt, 10, and son Dimitri, 8.

Last month, Kutcher and Kunis celebrated their 10th wedding anniversary in Venice, Italy. They were photographed on an outing in the Floating City, during which Kutcher sported a blue-and-white patterned shirt paired with khaki shorts while Kunis wore a blue-and-white floral patterned dress and flip-flops.

It seems the two stars enjoy musical date nights. Last summer, the couple attended Taylor Swift’s Eras Tour during its second night in London, alongside numerous other celebrities, including Jason Kelce, Kylie Kelce, Rachel Zegler and Hugh Grant.
