Hot mama!

While her daughters Kim, Kourtney and Khloe Kardashian showed off their tan legs on the E! Upfront red carpet in NYC Monday, Kris Jenner covered up her own stems but let her incredible curves speak for themselves.

Dressed in the celeb-fave Stella McCartney "Octavia" dress, the 56-year-old worked her ageless figure in the slimming, skin-tight blue and black number, which she complemented with black heels, a black clutch and an orange and black statement necklace.

Other stars who have taken a liking to the $1,595 frock that features black panels that give the illusion of a smaller waistline: Kate Winslet (who owns it in an array of colors), Lala Anthony, Liv Tyler and Gloria Estefan.

"This has become one of the biggest dresses of the year," Sasha Charnin Morrison, fashion director at Us Weekly, said in September. "It's a body-conscious dress that is so clever, and it's from a major designer. All of the groovy girls wear Stella. Everyone wants to wear her now."
