Music superstar Beyonce Knowles shows off her incredible post-baby bod in the latest campaign for her clothing line, House of Deréon.

In these newly released photos, Knowles, 30, struts her stuff in a number of ensembles.

Among her sexiest looks: a midriff-bearing black top, which she pairs with a black leather jacket and a revealing leopard-printed slitted skirt.

House of Deréon was conceived by Knowles and her mother, Tina. It launched in 2006.

On August 19, Knowles performed her song I Was Here at the United Nations in New York, as part of World Humanitarian Day.

She also released a new set of photos on her personal blog, some of which feature her daughter, Blue Ivy, born January 8. Check them out, below.
