It looks like nuptials are the new black in Hollywood these days. A whopping four stars put a ring on it this weekend, including Carrie Underwood, who married Mike Fisher; Martin Lawrence, who married longtime girlfriend Shamicka Gibbs; John Krasinski, who married Emily Blunt; and LaLa Vazquez, who married Carmelo Anthony. Carrie, the former American Idol winner, married Fisher in Georgia, in the presence of Simon Cowell, Paula Abdul and Randy Jackson, the judges who jumpstarted her career. Lawrence was last seen in Death at a Funeral, and his buds Eddie Murphy and Denzel Washington were at his Beverly Hills fete to congratulate him. Krasinski, of The Office fame, got hitched in an equally star-studded ceremony in Como, Italy, where George Clooney was in attendance. LaLa Vazquez, who's better known as Kim Kardashian's BFF, married her baller boy in New York City.
