Mila Kunis and Ashton Kutcher are a very private couple. They haven't even officially announced that they are dating, but are seen PDAing across the world, from Hollywood to France. Now rumors have surfaced that the pair are planning a U.K wedding at possible historic sites.

The Daily Star tabloid said a source "close to the couple" confirmed Mila and Ashton are ready to get hitched, and want the ceremony to be in Great Britain.

The source says the couple has "fallen in love with the U.K."

"They are desperate to get married as soon as possible because they want to start a family and are slightly old-fashioned about these things," the source continued.

The source also confirmed that the former "That 70s Show" costars are looking at historic British sites for the location of their nuptials, including Stonehenge and the Royal Pavilion in Brighton.

"Mila loves the idea of a stately home or something in the English countryside," the source said.

The source added that the wedding will be a private affair, with just a few close friends and family members.

Neither actor has come out to deny or confirm the rumors. However, Ashton recently met Mila's parents when they came to the U.K to visit their daughter, The Examiner reports.

The couple seems happier than ever. Mila and Ashton were caught smooching all over Saint Tropez, France, in rare incidents of PDA for the usually-private actors. A wedding, if true, probably won't happen soon. Ashton Kutcher has yet to finalize the divorce from his ex-wife Demi Moore.
