LONDON: The Sex and the City actress and hubby Matthew Broderick have reportedly picked Michelle Ross to carry their twin girls.

According to US reports, the 26-year-old has been surrogate mum for a New York gay couple before and is openly bisexual.

A magazine claimed she has her own biological son and has been criticised for neglecting him, while concentrating on giving the Hollywood actress her children.

Michelle, who is due to give birth in July, has also been pregnant once before but lost the baby before it was born.

Her miscarriage was thought to be linked to Guillain-Barre Syndrome, which she carried while pregnant.

The disorder causes the immune system to attack the body's nerves.

The magazine also reported that Rachel spoke of her 'pink hair, tattoos and spiked collars', on her MySpace profile, hinting that she has alternative fetishes.

She said: “My favourite shoes are five-inch black spike heels which lace up at the font...I love metal and rock down to the bones.”

Michelle was once married but now divorced and her ex-husband supports her decision to act as surrogate.

She has refused to confirm that she is carrying Sarah and Matthew's twins.
