Kristen Bell gave birth to baby Lincoln only two months ago but the new yummy mummy was back in fighting form when she hosted the 2013 CMT Music Awards on Wednesday.

Looking better than ever in her post-baby body, the former "Veronica Mars" star changed into not two, but four radically different outfits while performing her hosting duties alongside co-host Jason Aldean in Nashville. This was Kristen's second time hosting the awards and Jason's first.

So what did the notorious sloth-lover wear?

While working the red carpet, Bell wore a sexy black leather Zuhair Murad dress with delicate embroidery on the chest and a skirt which showed off her toned legs.

Once the 32-year-old hit the stage she channeled her inner glamazon warrior in a flashy gold and silver mini dress which looked like what a modern Bronze Age queen would wear.

The Michigan-native's next outfit change was a searing hot sexy black column dress with featured a T-strap neckline and plenty of baby mama cleavage.

Finally, Bell ended the night with a party-ready dress with a flowing skirt and a gem-encrusted bodice.

However the actress' most important accessory of the night was her breast pump! Kristen, who's been married to actor Dax Shepard since 2007, snapped a photo of her kit in her dressing room just before the show and captioned it "My new pre show beauty routine. #pumpit #pumppumpitup."

Better get used to it, Kristen!
