Denise Richards is adding another little girl to the bunch! The 40-year-old actress just adopted a baby girl domestically, her rep confirmed to PEOPLE on Wednesday.

"Eloise Joni Richards is named after Denise's mom (Joni), and Denise and her daughters Sami and Lola chose the name Eloise," the rep said. "Denise and Eloise's big sisters couldn't be happier and feel incredibly blessed."

Richards has two girls from her marriage to Hollywood bad boy, Charlie Sheen: Lola, 6, and Sam, 7.

Richards recently revealed she's writing a memoir. "I get into the good stuff about my marriage, because people have only read the rotten stuff," she said, referring to her marriage to Sheen. "So, you know, there was a beautiful love story between he and I and then it went the way it went."
