Kim Kardashian can pull off daring designer duds and the fiercest of footwear – not to mention her knack for leopard-print looks. But the queen of reality TV proved that she's still gorgeous without all the glitz and glamour.

In a self-portrait she posted on Twitter early Tuesday, Kardashian, 31, rocks a sports bra and a pair of matching sweatpants with her red-carpet confidence (and signature curves!) on display.

"Sweatpants hair tie chillin with no make up on," she wrote, quoting Drake's R&B hit, "Best I Ever Had."

The natural look is a departure for Kardashian who told PEOPLE that she loves getting glammed up when she was selected as one of 2011's Most Beautiful.

"I feel most beautiful when I'm fully in hair and makeup in the middle of a photoshoot," she said. "I'm not going to lie and say that I spend a lot of time without makeup on. I really don't. I feel more myself, and I feel prettier when I have makeup on."
