Brooke Mueller attended the 9th Annual Chrysalis Butterfly Ball Saturday -- her first public event since her drama with Charlie Sheen.
“My best friend Rebecca Gayheart and I have been a part of this charity for several years and it’s a great cause," she told UsMagazine.com.
She said her 1-year-old twin sons Max and Bob "are great."
Asked if she has any summer plans, she told Us: “Not that I know of.”
Sheen, 45 -- who was arrested Christmas Day following a fight with Mueller, 32, in Aspen, Colo. -- is expected to plead guilty to a misdemeanor offense July 7.
