The Hollywood stars became engaged last year (14) and welcomed their first child, a daughter named Wyatt, in October (14).

They were recently rumoured to have exchanged vows in secret after Kunis was spotted wearing a band on her left hand, but a new report suggests the couple will officially wed at a private mansion in Los Angeles over the Independence Day weekend.

A source tells New York Post gossip column Page Six, "Details are being held close to the vest and were expected to go out to guests 24 hours or less before the wedding. It is going to be a very small and intimate affair with friends and family."
