Mila Kunis' baby bump concealed as boyfriend Ashton Kutcher aggressively confronts paparazzi? Pregnancy rumors loom [VIDEO]

Former "That 70s Show" co-stars Mila Kunis and Ashton Kutcher continue keeping their romantic relationship on the down-low. But, is the couple actually hiding something else from the public?

According to TMZ, Kutcher "aggressively" confronted members of the paparazzi outside of Hollywood's Carlitos Gardel Restaurant last night (Monday, Nov 25). Apparently he did that so girlfriend Kunis could escape without being bombarded by photogs. Wonder why? Check out the footage here.

TMZ and other gossip outlets report that "the whole tough guy act may have just been a cover to keep his allegedly pregnant girlfriend away from cameras."

Apparently, several papparazzos were shocked that Kutcher got so hostile, considering that part of Hollywood is known as a "heavily-trafficked celeb sighting area."

During this "confrontation" (where Kutcher allegedly "tried to strong-arm the photogs into leaving the scene") Kunis was spotted sneaking off in the background with one of Kutcher's associates. They quickly hoped into a waiting car without being bothered.

The "Hottest Woman Alive" was flaunting a baggy pair of jeans and an oversized sweatshirt... perhaps she's trying to hide a baby bump?

As TMZ points out:

"...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."

Meanwhile, a source close to the situation tells Gossip Cop that such pregnancy rumors are "100 percent not true." Perhaps Kunis just wanted some privacy, and Kutcher was being a gentlemanly boyfriend!

So, what do Mstars fans think? Are a secret baby and wedding on the horizon?
