Singer bares her bod

Fergie has put her incredible post-baby on display.

The singer – who welcomed son Axl Jack last August – stripped down to a tiny pair of knickers to shoot a new Calvin Klein promo.

Boom. #mycalvins,’ Fergie captioned the clip on Instagram yesterday.

Josh Duhamel‘s wife, 40 – who wears her hair in waves as she writhes around on a bed – caused quite a stir with the footage.

WOW PLEASE DON’T PHUNK WITH MY HEART GIRL,’ exclaimed one fan.

Another added: ‘Too hot to handle!
