Jennifer Lopez has started IVF treatment

(BANG) - Jennifer Lopez has reportedly turned to IVFtreatment in a bid to get pregnant.

The singer-and-actress - who is married to Latin star Marc Anthony - is said to be desperate to have two children and has been talking to patients at the IVF - In Vitro Fertilisation - clinic in Los Angeles' Cedars-Sinai Medical Centre.

A source told Britain's The Sun newspaper: "Jennifer said she wanted to have two children. She said she'd recently started IVF treatment and couldn't wait to have a family."

The 37-year-old 'Maid in Manhattan' star, who recently said she would "do anything to get pregnant", has also tried eating spinach after she learnt it could make her more fertile.

J.Lo has been eating the leafy vegetable three times a day to boost her intake of folic acid, on her doctor's recommendations.

She said: "I've been on spinach omelettes for breakfast, spinach salad for lunch and sauted spinach with every dinner.

I guess if the spinach doesn't help me conceive, I'll still end up with Popeye-sized muscles."

Last month, Jennifer's spokesman rubbished reports she was expecting her first child, after US pop star Jesse McCartney told a radio station she was pregnant.

The spokesman said: "She is 100 per cent not pregnant."
