Mariah Carey is allegedly already married to Nick Cannon. A source told Latina.com that the couple wed yesterday in a small ceremony on an island and it was "very impulsive." Da Brat also attended, the website claims.

The 38-year-old singer and song writer has been dating Cannon since they met on the set of her last video. The couple attended the TriBeCa Film Festival to promote their forthcoming movies.

A big diamond wedding ring on the finger at the TriBeCa Film Festival set out rumors that Mariah Carey is engaged to actor Nick Cannon. Canon, 27, a star of MTV's Wild & Out, came to the film festival to endorse his latest role in “Ball Don’t lie”, while Carey came for her role in the movie “Tennessee”.

The two stars held hands at the festival’s after-party. Mariah wasn’t shy at all about the new jewel. She gladly showed it off her huge diamond ring that caught the attention of many. Some reports claim that it is actually a second-hand ring, which appears to be identical to the one that Nick Cannon gave his former fiancée, Victoria's Secret model Selita. Perezhilton.com also confirmed that it is the same ring. Not cool!

According to a recent report from People magazine, the couple subsequently took a private jet into Las Vegas. The two were seen getting intimate in a VIP section of a nightclub.

Carey is on a good wave this year – her most recent studio effort, the not so formulaic “E=MC2,” has sold 463,000 copies, becoming her sixth No. 1 album on the U.S. pop chart, scoring the highest debut of the year by any artist so far. Last month, she surpassed Elvis Presley on the Billboard charts as the solo artist with most No. 1 singles, by reaching her eighteenth No. 1 with her latest single, “Touch My Body.”

Barbra Streisand remains the female artists with most No. 1 albums, eight, while Carey, Madonna and Janet Jackson tie for the second most No. 1 albums.

Mariah Carey has been married with Tommy Mottola. The two got married in 1993 three years after Mariah made her debut under Mottola’s guidance. They divorced in 1998.

Last year, Nick Cannon called off his engagement to model Selita Ebanks. During an interview with MTV US, he did everything he could to avoid a confirmation of the relationship with Carey. However, he gave a hint: “Rumours happen”. He participated early this year in a will.i.am-produced music video for Barack Obama entitled "Yes We Can."
