The 45-year-old singer, who recently sparked rumours she is in the process of rebuilding her marriage to estranged husband Nick Cannon following their split last year, has hinted she might be in a relationship again.

Asked if she thinks she will fall in love in Las Vegas, where she is set to kick off her residency at Caesars Palace next month, she said: "Darling, who knows if I already have or have not? Anything and everything is possible."

Mariah, who has three-year-old twins, Monroe and Moroccan, with Nick, has already relocated with them to the city and hinted Nick, 34, will also be spending a lot of time there.

She said: "They're always with me. They're with me or they're with their father. It is what it is and I would never just be like, 'I'm going, you're not going to be with me.' They wouldn't understand that. So they're the most important thing to me. Their family is going to be here. They're going to be great. They do their own thing."

Meanwhile, the '#Beautiful' singer is currently trying to get in shape for her concert series.

She told E! News: "I've been trying to get there. I'm a regular person. It is what it is.

"The rehearsals have been going really well. It's been mainly for me about the music and about how to incorporate the songs. Just because they were all number one records doesn't mean they all make an easy set list...a lot of ballads and up tempos. So it's difficult to make it work seamlessly."
