Mariah Carey's husband bought her a dog as an anniversary present.

Nick Cannon treated the singer to a Jack Russell terrier as an early present ahead of their one-year wedding anniversary in May.

The actor-and-rapper said: "I got her a short-haired Jack Russell terrier - a girl named Cha-Cha. She's eight weeks."

Nick has revealed they could have a second wedding to mark the anniversary of their low-key nuptials in the Bahamas last April.

Nick - who will host the next series of 'America's Got Talent' - said: "We have spoken about it, and it's coming up - that's all I can say. We are going to do what we said we were going to do from the very beginning."

Mariah has also hinted they may celebrate their marriage again, saying: "Nick's plan is to have one wedding every year. I think instead of trying to be like, 'You're invited, but shhh, don't tell anybody.' "
