Ashton Kutcher and Mila Kunis are husband and wife after secretly getting married over Independence Day weekend (03-05Jul15).

Sources have confirmed to People.com the couple tied the knot, but details of where and when the ceremony took place have not been revealed, and the couple's representatives have yet to comment on the reports.

Kutcher, 37, and Kunis, 31, met as co-stars on hit TV comedy That 70s Show in the late 1990s, but they did not start dating until his marriage to Demi Moore ended in 2011.

The actor proposed to Kunis in February, 2014, and she gave birth to their first child, Wyatt Isabelle, in October (14).

News of the top secret nuptials were leaked to the New York Post late last week (ends05Jul15) - a source close to the couple told the publication, "It is going to be a very small and intimate affair with friends and family."

Kutcher and Kunis were not the only celebrities celebrating weddings over the weekend - Billy Joel wed his pregnant girlfriend at his annual Independence Day party in Long Island, New York on Saturday (04Jul15), the same day singer/actress Vanessa Williams exchanged vows with retired accountant Jim Skrip.
