Out actor George Takei on Friday cheered a ruling striking down Arizona's ban on gay marriage.

The 77-year-old Takei, who is best known for his role as Hikaru Sulu on Star Trek, married husband Brad Altman in 2008 in California, where the couple lives.

“Brad and I consider Arizona our second home, and we couldn't be more thrilled,” he tweeted to his more than 1.4 million followers. “Welcome to the right side of history.”

Gay and lesbian couples began marrying in Arizona moments after Attorney General Tom Horne announced his office would not appeal the ruling.

The first couple to receive a marriage license in Arizona have been together nearly 57 years. The women met in college but did not discuss their relationship with their families until 2008. The first couple to marry did so during an impromptu ceremony outside a government office in Phoenix. One of the grooms raced from the gym to join his future husband.
