Rapper/actor Nick Cannon squirmed awkwardly when asked about his rumored engagement to Mariah Carey during an MTV News chat on Monday, refusing to deny reports he'd asked the pop superstar to marry him.

Carey sported a huge diamond ring on her wedding finger at the Tribeca Film Festival in New York at the weekend, fueling speculation she is to wed for a second time. And rumors that Cannon is her new man refuse to go away.

Promoting his new film in New York on Monday, the MTV regular refused to make eye contact with his interviewer when he was asked about the alleged engagement.

Chuckling nervously, Cannon said, "Rumors happen, they do. She's a great person... She' probably the most festive, remarkable person I've ever met."

Carey's representatives have refused to comment on the new wedding rumors. She was previously married to Columbia Records executive Tommy Mottola, they divorced in 1998 after five years.
