Not everyone was at Sunday's Emmys.

Mila Kunis and her sweetie Ashton Kutcher snuggled on the sidelines of the NFL game between the Pittsburgh Steelers and the Chicago Bears at Heinz Field on Sunday in Pittsburgh.

On Friday, at a pre-Emmy party in Beverly Hills, their That '70s Show co-star Laura Prepon spilled to Us Weekly that she "wasn't surprised" Kutcher, 35, and Kunis, 30, had reunited after first meeting on the set of the 1998-2006 show. (Do the math: They would have been 20 and 15 at the start of the show.)

In fact, she revealed that Kutcher, 35, was Kunis' first kiss. "He was. He was," she confirmed. Kutcher and Kunis' characters, Michael Kelso and Jackie Burkhart, dated on the show. "They're like my family," added Prepon, who says they've all kept in touch.
