Dozens of female celebs stepped out to take part in the 25th Day of Indulgence, an annual event held by film and TV producer Jennifer Klein at her home in Los Angeles.

Jennifer brings together women in Hollywood every year and creates an environment where they can catch up and relax, while also indulging in yummy treats, delicious drinks, and the hottest new items in fashion, beauty, and more.

Kaley Cuoco, Kelly Rowland, and Christina Hendricks are just some of the many stars who attended the event on Sunday (August 13) at Jennifer‘s home in Brentwood, Calif.

“It’s just like a nice girl’s afternoon,” Kaley told InStyle at the event. “It’s really sweet to be able to bond with other women. Our business is so in flux right now. So, it’s nice to be able to do this and get together.”
