Walter Koenig to be George Takei’s Best Man, Nichelle Nichols as Matron of Honor

Every trekkie’s head just exploded:

The 71-year-old star, known for his role as Sulu in the 1960s sci-fi series, will wed partner Brad Altman this summer, after California state authorities lifted the ban on same-sex marriage last month. Takei will marry his partner of 20 years on September 14 and has invited his former castmates to the ceremony. He tells People.com, “The best man is my colleague from Star Trek, Walter Koenig, who played Chekov, and the matron of honor is Nichelle Nichols (Lt. Uhura). And Leonard (Nimoy) and his wife Susan are on the (guest) list.”
