Mila Kunis and Ashton Kutcher make a lovely couple, so much so that pregnancy rumors are now spiralling across Hollywood gossip sites. And the most recent issue this sweet couple is facing involves a rumored bun in the oven. So how true is pregnant rumor? Let's find out.

Before anything else, let us take a look at where this rumor officially came from. And our sources point People magazine, which published an article saying that Ashton is already planning his proposal to Mila, and that the two are not willing to waste any more time.

"They both want kids. It's something they're vocal about. I can't imagine it will be very long before she's pregnant. [Maybe] right after they get engaged if not sooner. Ashton is definitely planning a proposal. They're incredibly affectionate. It's completely effortless," a "friend" of Ashton's revealed to the magazine.

Following this news is the speculation that Mila Kunis may already be pregnant. This was of course based on the fact that the actress is fond of wearing loose-fitting clothes recently.

Then, came the big hint when TMZ reported that Ashton and Mila where spotted recently walking out of a Melrose Avenue restaurant following a friendly dinner with some of their closest friends. TMZ added that it was not like any other normal encounter with the couple.

Kutcher was said to have displayed a tough guy act in protecting his girlfriend from the paparazzi. All the while Mila, who was wearing a loose-fitting clothing, walked behind her boyfriend as though trying to cover the baby bump.

"The whole tough guy act may have just been a cover to keep his allegedly pregnant girlfriend away from cameras. Ashton and Mila Kunis were eating dinner at Carlitos Gardel Restaurant in Hollywood and it also happens to be smack in the middle of a heavily-trafficked celeb sighting area. And why would she want to go under the radar? There are rumors that Mila's knocked up... and photos of the actress could fetch top dollar around town," TMZ noted.
