Actor John Barrowman shocked fans on Tuesday (02Jul13) when he announced plans to wed his longtime partner - as the couple made its way to the California ceremony.

The Torchwood star has been with Scott Gill for almost 20 years, and after officials at the U.S. Supreme Court struck down the Defense of Marriage Act and overturned California's Proposition 8 last week (26Jun13), they decided to make their union official.

The Scottish-born performer shared the news with fans by uploading a video of the couple en route to its nuptials on social networking site

In the footage, Barrowman says, "We're getting married in the state of California. Thank you Supreme Court, about time you made it legal. See you after we have the ceremony!"

The Supreme Court's landmark double ruling provides equal benefits rights to same-sex spouses across the nation and allows gay marriages to resume in the West Coast state.

The pair had previously exchanged vows in a civil ceremony in the U.K. in 2006.
