Kathryn Merteuil is back and badder than ever in the Cruel Intentions reboot!

Sarah Michelle Gellar opened up to ET about reprising her scheming evil stepsister character for the TV reboot of the cult classic 1999 film, which has a pilot order from NBC, at the United Way Women's Summit in Beverly Hills, California on Monday.

“It’s 17 years later and we didn't tell the story until we had a great story to tell,” the 39-year-old actress explained. “I think we have something really unique and really different.”

The reboot will pick up 15 years after the original Cruel Intentions plotline, and focus on Bash Casey, the son of Sebastian Valmont (Ryan Phillippe from the original film) and Annette Hargrove (Reese Witherspoon). No doubt Bash’s Aunt Kathryn will play a sinister hand in things as he unravels his father’s life and legacy from journals he left behind.

Gellar has been excitedly documenting her return to character on social media, and gushed to ET that the new series will be “better, badder… can you say bitcher?” (Yes. Yes you can.)

Apart from the exciting throwback, Gellar has also been hard at work on her Foodstirs baking brand, and says her “greatest inspiration” for the company is her children: 6-year-old Charlotte and 3-year-old Rocky.

“For them to watch us have an idea, take it from inception to creation to an actual product, to seeing it online and seeing it in stores you can't beat that,” she gushed. “Ultimately, as a parent, you want teach your children that they can accomplish anything and to be able to show them that journey, it's priceless.”

But, Gellar admits that it’s husband Freddie Prinze Jr. who truly runs the kitchen in their house.

“He's really the expert,” she said. “I bring the experience and the sweet treat, but he's the main man real deal experience in the kitchen.”
