Nick Cannon attended Mariah Carey's birthday party a little more than a month before their surprise wedding in the Bahamas.

Carey – who turned 38 on March 27 – celebrated with her "posse," including rapper Da Brat and nephew Shawn McDonald on a private island off the coast of Antigua, Vibe magazine reports in its June issue.

Vibe described Cannon, 27, as a "recent acquaintance." He was spotted with his laptop. He also fixed himself a plate at the buffet, the magazine reports.

Her nephew Shawn, who previously alluded to attending the secret wedding on Facebook, gave an "eloquent toast" at the birthday bash, Vibe reports. Carey paid for his Cornell undergrad and Harvard Law Education, the magazine also reveals.

Carey and Cannon wed at her home in Eleuthera in the Bahamas this week, the New York Post reported after Latina magazine broke news of their marriage Thursday.
