Mariah Carey has been visiting a fertility clinic.

The 38-year-old singer who married her husband Nick Cannon 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 the natural way, they visited a fertility clinic to help make their baby dream come true."

Mariah is said to be desperate to give birth before she turns 40 next March.

The renowned center is one of the leading in-itro fertilization (IVF) clinics in California.

The couple have made no secret of their desire to start a family, with Nick admitting he wants a large brood. He said: "We'll multiply. That's what's got to happen."

Mariah has also revealed she is ready to become a mother but tires of the constant speculation about whether she is expecting.

She said: "I don't like to talk about it too much. I just think about it as the next phase. We'll see."
