Mariah Carey Tickets

Mariah Carey has shared a photo of herself and husband Nick Cannon in a Valentine's Day card, with her Twitter followers.

The 'We Belong Together' singer can be seen posing with her radio presenter hubby in a heart-shaped frame with the words: "There's only one forever" written in another red heart.

Another message on the e-card read: "Happy Valentine's Day to all the Lambs! Love always, Mariah & Nick."

Not forgetting the person whose songs have become almost the sponsored soundtrack to the love-filled day, Mariah paid tribute to Whitney Houston who sadly died over the weekend.

"A bittersweet Valentine's day... I hope everyone can share today with their loved ones," she wrote in reference to Whitney.
