Rebecca Gayheart couldn’t be more proud: daughter Billie Beatrice is officially on the run — sort of.

“Now she’s running and it gets kind of scary because she looks like a drunk baby weaving around the house,” the actress jokes to PEOPLE at the 10th Anniversary Chrysalis Butterfly Ball in Los Angeles on Saturday.

But becoming mobile isn’t the toddler’s only latest milestone, according to Gayheart, 39.

“She’s mastered a few words. I think she has about four words now and she’s just 15 months old, so I think we’re okay,” she laughs, revealing both “ball” and “duck” have recently been added to Billie’s vocabulary.

Happy to divulge details about her only child with husband Eric Dane, Gayheart isn’t so willing to share — or sure of! — her plans for upcoming Father’s Day.

“He already celebrated his first Father’s Day last year, and this is really embarrassing, but I’m not sure what I’m getting him yet [this year],” she giggles. “Let’s not discuss that!”
