Sarah Michelle Gellar looks stunning post pregnancy and has lost oodles of weight. The “Buffy the Vampire Slayer” star gave birth to a baby boy in September and seems to have lost all her pregnancy weight in just a month.

The star was spotted by us magazine along with her 3-year-old daughter Charlotte in California. Dressed in tight-fitted blue jeans and a gray T-shirt, the star carried little Charlotte and beamed at her. Sporting loose hair and aviator shades, the star towered in high-heeled snakeskin boots. This is Gellar’s first appearance after the birth of her second child, a son.

Gellar is married to Freddie Prinze Jr. who she met during the filming of 1997 teen horror film “I Know What You Did Last Summer”. The couple married in 2002 in a private ceremony in Mexico.

Gellar has a very distinctive sense of style, and it looks like her daughter will grow up to be the same. Charlotte is said to have chosen her own apparel for the 2012 Golden Globes Award, in which her mom walked the red carpet in a show-stopping Monique Lhuillier Spring 2012 gown. Gellar carried off the water-colored designer dress with exaggerated layers beautifully, accessorizing with a high and sleek pony tail and sultry, smokey eyes.

Gellar appeared at the 2008 Emmy Awards looking very graceful in a blue Vera Wang backless dress that complimented her extremely toned back.

Gellar also seems to be quite a tattoo fanatic, as she has been inked four times. The star has a symbol for integrity on her lower back, the symbol for patience, two dragonflies on her back and a cherry blossom on her ankles.

After this appearance which showed off her svelte and trim figure, Gellar joins the clan of yummy mommys like Salma Hayek, Gwenyth Paltrow, Jennifer Garner, Victoria Beckham and Gwen Stefani, to name a few. And the star is not only a yummy mommy, but also a tough mommy, with a black belt in taekwondo to her credit.
