Mariah Back From Bahamas and Ready to Warble

Newlyweds return to States a week after wedding; Mariah prepares for headlining gig

Hollywood's hottest newlyweds are home.

A week after their under-the-radar Bahamas wedding, Mariah Carey and Nick Cannon have returned to the States and are primed to resume work.

Nick's 18-year-old brother, Reuben Cannon, says his newly hitched brother is currently in Los Angeles.

"He's here, and he is really happy," Reuben, an L.A.-based professional singer and dancer, exclusively tells E! News.

"I've never seen him so happy."

Reuben declined to comment on the whereabouts of his new sister-in-law, but a source says Carey was in the City of Angels as of Tuesday.

She's not staying long, though.

A rep for Time magazine's Time 100 gala, set for Thursday night in New York, confirms to E! News that the bash will be headlined by the new Mrs. Cannon.
