Giuliana Rancic is one hot new mama!

Returning to work to anchor E!'s Emmy coverage Sunday less than one month after her son, Edward Duke, was born via surrogate, Rancic looked effortlessly chic hobnobbing with the stars on the red carpet.

Opting for an ivory Rafael Cennamo dress that matched co-hosts Kelly Osbourne (in Marcia Lucia Hohan) and George Kotsiopoulos (in Brooks Brothers), the new mom, 37, accessorized her look with Forevermark jewels, a Judith Leiber clutch and Giuseppe Zanotti heels.

Later, when it was time to join Ryan Seacrest to anchor the night's main event, Rancic switched up her look quite drastically. Taking a cue from Angelina Jolie at the 2012 Oscars, Rancic showed quite a bit of leg in a sleek Romona Keveza gown with a thigh-high slit.

To add polish to her strapless black number, the journalist slipped on Jimmy Choo shoes, Sutra earrings and made sure she had a sun-kissed glow thanks to Infinity Sun.

Rancic wasn't the only one to brave L.A.'s scorching heat in a black Emmy ensemble. Newly single Amy Poehler, Glenn Close, January Jones and Melissa McCarthy were among some of the other stars who rocked the tried-and-true hue.
