Will Kelso and Jackie have a happily ever after? Engagement rumblings are a-flying around former "That '70s Show" lovebirds Ashton Kutcher and Mila Kunis, despite the fact that the actor isn't yet divorced from Demi Moore. The reason for the rampant betrothal talk? The starlet flashed a plain gold band on her ring finger as she shopped for flowers on Wednesday in Los Angeles (see photo at left).
The couple's reps remain tight-lipped, and insiders deny they're engaged, but sources tell People that Ashton, 35, and Mila, 30, "may have some exciting news to share" soon.
Seems he recently dropped hints about proposing around the actress' milestone birthday on Aug. 14.
"He knows what they have is amazing and special," says a Kutcher confidant. "He's been thinking about proposing for a long time."
Adds another spy, "They are clearly very much in love, in tune with each other and so comfortable. In some ways, it's like they're married already."
That might explain why Mila is wearing a simple band instead of a sparkler. Besides, Kutcher is still technically hitched to his first wife.
He and Moore split in November 2011, not long after he allegedly got up close and personal with a blonde on what would have been his sixth wedding anniversary.
He filed for divorce in December 2012, eight months after he first stepped out with Mila. But the proceedings have reportedly grown contentious over money, specifically, the many millions Ashton has earned from his various high-tech investments. One estimate put Demi's demands in the $25 million range.
The divorce delay hasn't dampened the "Two and a Half Men" star's enthusiasm for diving into a joined-at-the-hip romance with Mila. They've enjoyed PDA everywhere from Los Angeles to Beijing.
And the low-profile pair are said to be actively planning a family.
"They're not not trying," an insider told People in August. "They would be thrilled if Mila were to get pregnant, whether or not they are married."
