Is Ashton Kutcher's girlfriend Mila Kunis pregnant? Ashton Kutcher and Mila Kunis were spotted on a dinner date on Monday night, and Mila Kunis was wearing baggy clothes. Is Mila Kunis pregnant and hiding her baby bump?

According to TMZ, Ashton Kutcher and his girlfriend Mila Kunis were spotted leaving the popular restaurant Carlitos Gardel in Hollywood on Melrose Ave. The "Black Swan" actress wore an over-sized white sweatshirt with a cute ice cream cone print on the front, with baggy boyfriend jeans and flat white shoes. Her hair was tied in a casual bun and she carried a doggy bag.

Why did Mila Kunis opt for such a baggy outfit on date night? Is it possible that Mila is pregnant and hiding a growing baby bump?

The couple - who have been dating each other for over a year - looked comfortable and happy together...until Ashton saw that photographers were following them. TMZ reports that Ashton " got aggressive with the paparazzi" and tried to get the photographers to leave the scene. Was he protecting his pregnant girlfriend?

As we previously reported, a source says Mila and Ashton are already looking forward to starting a family.

"They both want kids. It's something they're vocal about," a source close to Ashton told People magazine, The Daily Mail reports. 

"I can't imagine it will be very long before she's pregnant. [Maybe] right after they get engaged if not sooner," the source speculated.

"Ashton is definitely planning a proposal."

"They're incredibly affectionate. It's completely effortless," the source added. "Ashton's really found 'the One' with Mila. His family adores her."

'If something is important to [Mila], he'll do it with a smile on his face without her even asking. I've never seen him so happy," the source said.

Ashton, 35, and Mila, 30, both former "That '70s Show" co-stars, were first rumored to be dating in April of last year.
