Over the weekend, Takei announced on his Web site that he and long-time partner Brad Altman will get married this summer.
"Our California dream is reality," he wrote. "At long last, the barrier to full marriage rights for same-sex couples has been torn down."
Takei, who also had a reoccurring role on "Heroes" last year, first came out in 2005 in order to talk against a veto by California Gov. Arnold Schwarzenegger of a same-sex marriage law.
