Mariah Carey received an extra special 40th birthday present this weekend - her husband Nick Cannon bought her a custom-made pink Porsche to mark the milestone.

The Hero hit-maker turned the landmark age on Saturday and she was delighted with her gifts from Cannon, who she married in 2008.

Taking to her Twitter.com blog to reveal the special surprise, she writes, "Thank u (sic) everyone for the anniversary wishes! Today is a 'smash hit wonder' I'm having SO much fun & you guys make everything even better... All the videos and messages I got for my anniversary were incredible. You never cease to amaze me and make me happy and grateful..."

"Again, thank you so much to all who gave so much time & love... NC (Nick Cannon) shocked me with a custom PINK porsche!!! And a huge trampoline! Yes, pink."
