Nick Cannon: 'I won't be able to top Mariah Carey's anniversary baby gift'

Nick Cannon fears he'll never be able to better his wife Mariah Carey's fourth wedding anniversary gift to him - twins.

The entertainer watched amazed as the R&B superstar deliver the babies on Saturday morning (30Apr11) - four years to the day he wed Carey in the Bahamas.

Tweeting about becoming a first-time father, he wrote, "My wife just gave me the most incredible anniversary gift ever in life! I won't ever be able to top this!"

He later added, "I'm in the happiest place I've ever been in my life. I never had more amazing things happening. I am humbled by God's Favor!!"

Cannon was prepared for the anniversary arrival of his twins - he predicted they'd be born on Saturday in TV interviews last week (ends29Apr11).

Asked if Carey had planned to deliver the babies on Saturday, the singer's publicist Cindy Berger said, "Not even Mariah could plan that."
