Mariah Carey has been visiting a fertility clinic. The 38-year-old singer and her husband Nick Cannon - who married last year following a whirlwind romance - were seen leaving a Beverly Hills' Southern California Reproductive Center last week, where they reportedly met with a prenatal specialist.

A source told gossip blogger Perez Hilton: "Nick and Mariah are trying anything and everything to conceive. After almost a year of trying to natural way, they visited a fertility clinic to help make their baby dream come true."

Duffy's shyness almost stopped her from becoming a singer. The Welsh songstress - who picked up the Best Pop Vocal Album prize for her debut LP Rockferry at this month's Grammy Awards - nearly chose swimming over singing because of her nerves.

She said: "As a kid, I never wanted to be a singer - I was far too shy - but I needed a way of externalizing my thoughts because I was always talking s**t. I used to be a good swimmer but I got picked on in the pool."

Duffy wants to sound like Mariah Carey. The Welsh singer, whose retro tones won her Best Pop Vocal Album at the Grammy Awards on Sunday, reportedly intends to explore a more modern sound now she has established herself on the world's music scene.

A source told Britain's Daily Star newspaper: "She is keen to explore a Mariah or Christina Aguilera style of album. On the next record Duffy can afford to be a bit more experimental now that she is assured her position as a singing force to be reckoned with."

Mariah Carey was left "furious" after being told she wouldn't be sitting with U.S. President Barack Obama's family during his inauguration.

The "Touch My Body" singer - who performed at a ball to celebrate Obama being sworn in - was left aghast when she discovered she had to sit with other celebrities during Tuesday's ceremony.

Nick Cannon likes being known as "Mr. Carey." The actor-and-rapper - who married Mariah Carey following a whirlwind romance last year - doesn't mind when people say his wife is more famous than him, claiming he just takes the teasing in his stride.

Asked how he feels when people say cruel things about his wife, Nick replied: "My heart goes out to my wife every time she has to hear something like that. I don't care about nothing, I'm just silly. I make fun of me all the time, I'm like, 'Call me Mr. Carey, who cares?'"
