Mariah Carey and rapper Nick Cannon have tied the knot in a "very impulsive" ceremony in the Bahamas, it was reported Thursday.

The Long Island songstress said "I do" in front of a handful of friends, including longtime pal and rapper Da Brat, Latina magazine reported.

It was only days after she was seen at a Tribeca Film Festival after-party with Cannon on her arm - and a huge jewel-encrusted diamond ring on her finger. Sources close to Carey confirmed then that the pair were engaged, the TV show "Access Hollywood" said.

The couple met in March, when Cannon directed the video for Carey's new single, "Bye Bye," and started a romance that a source told Us Weekly was "hot and heavy." A month later, they were seen sharing a romantic night out in Las Vegas.

Carey, 38, left New York's Tenjune nightclub on Saturday with Cannon, 27, and the massive diamond - which bears a striking resemblance to one Cannon gave then-fiancée and Victoria's Secret model Selita Ebanks last year.

They'd been partying at an after-party for the Tribeca Film Festival's screening of "Tennessee," in which she stars. The ring has a huge, rectangular-cut clear diamond, surrounded by smaller jewels on an encrusted band.

Ebanks told Us Weekly, "I have no comment but wish them well." Cannon told MTV News this week, "[Carey is] probably the most festive, remarkable person I've ever met."

It's the second marriage for Carey, who divorced record executive Tommy Mottola in 1998 after five years.

Cannon ditched Ebanks last year.

Reps for the couple could not be reached Thursday.
