Fergie is apparently enjoying a healthy sex life during her pregnancy.

The Black Eyed Peas singer is expecting her first child with her husband, actor Josh Duhamel. It seems that Fergie is feeling rather frisky during the sixth month of her pregnancy.

'Fergie says her libido has gone wild! She says they've been having sex two or three times a day,' a source told British magazine Closer. 'She's making the most of all the sex now as she's been warned they might hit a dry spell after the birth!'

Insiders close to Fergie also say that the prospect of having a baby has brought her 'closer than ever' to Josh.

The 38-year-old star has flourished during her pregnancy and is enjoying seeing how her body has changed in the past few months. Josh is also said to be a fan of Fergie's newfound curves.

'Fergie said she's never felt so empowered,' the source added. 'She's really embracing her new body shape and Josh is showering her with lots of compliments.'

The singer announced her happy news on Twitter in mid-February and later revealed she was 'thrilled' to be starting a family.

She also recently admitted to feeling unprepared for the arrival of her first baby.

"I have no idea what I''m doing," Fergie laughed. "I''m just going to play it by ear and see how things go, and let the natural instincts kick in."

To help combat the initial symptoms of morning sickness and tiredness, the star relied on acupuncture and Chinese herbs.
