Nicole "Snooki" Polizzi didn't get all dolled up for Wednesday night's first Presidential debate between Barack Obama and Mitt Romney.

The Jersey Shore star and new mom, 24, had a casual, no-frills night at home -- which meant absolutely no cosmetics.

"Legit loungin in pjs & no makeup," Snooki tweeted of an Instagram photo, in which she flashes a huge, completely fresh-faced smile from her living room. "I feel good." Behind the star in the snapshot: A baby seat plus a television, with the tell-tale split screen of Obama, 51, and Romney, 65.

In another snapshot from the same night, the pint-sized former party girl snuggles with Lorenzo, her month-old son with fiance Jionni LaValle.

"Cuddlin with my dream boy," she writes of Lorenzo, still sporting a full head of dark hair and wearing a polka-dotted onesie. (Her bundle of joy was born Aug. 26.)

Snooki found time during the debate to put down Lorenzo and continue to hone her post-baby body, too: "Crunches and debate!" she wrote in another photo, showing a blurry shot of her figure from the neck down as the Presidential contenders duke it out on Fox News.

On Thursday night, it's Snooki herself who'll be on the small screen, with the final season of MTV's The Jersey Shore debuting.
