Jessica Simpson denies carrying twins

Jessica Simpson has dismissed claims she is carrying twins.

The singer turned designer is expecting her first child with fiance Eric Johnson and she announced her pregnancy in October after weeks of speculation surrounding her growing baby bump.

Simpson has now revealed she won't find out the sex of the baby until the birth as she will struggle to keep the news quiet, but she does know that it's not double trouble.

She tells Ryan Seacrest: "I'm a loudmouth. There's no way (I will find out the baby's gender)... I eventually want both (a boy and a girl) so I'll be happy with either one, but it's definitely not twins."
