Canoodling like a pair of teens on the streets of New York last week, it was clear that Ashton Kutcher and Mila Kunis are very much in love. As Ashton, 34, leaned in to whisper in her ear, 29-year-old Mila dissolved into fits of laughter and then moved in for a smooch. It’s no wonder some of the hundreds of onlookers at first wondered if the two actors were in the middle of filming one of the mushy romantic comedies they’re so famous for.

The lovestruck couple have been in a relationship for just five months but already those closest to them are saying a walk down the aisle – and even the And the breakneck speed of the romance comes as no surprise to those around them. “This is more than just a honeymoon period,” a mutual friend – who has know the pair since they met on the set of That ’70s Show 14 years ago – tells Woman’s Day.

“Because they’ve known each other so long, they know everything about each other. It’s ridiculous to think of this as a five-month relationship. It’s really a 14-year relationship.” It’s no secret that Ashton is ready to have babies, with some friends believing it was the underlying cause of his scandal-laced split from wife Demi Moore, 49.

“Ashton feels that his biological clock is ticking,” a source told US Star magazine recently. “He has wanted kids for ages but he and Demi didn’t have any luck conceiving, mostly because of her age.” Fortunately for Ashton, Mila is keen to have children soon, too. She recently stated she wants a family within the next five years, adding, “I think in this industry, people have a short shelf life, truly.”
