Billie Lourd's kids will "freak out" about her Smurfs role.

The 32-year-old actress stars in the new animated movie alongside the likes of Rihanna, James Corden, Sandra Oh, Jimmy Kimmel, Octavia Spencer, Alex Winter, and Hannah Waddingham, and Billie is convinced that her kids will love the film.

Billie - who has son Kingston, four, and daughter Jackson, two - told People: "I just love to do anything that they'll care about."

The actress - who previously appeared as Lieutenant Connix in the Star Wars sequel trilogy - is "so excited" for her kids to watch the new movie.

She said: "This might be my career peak because it's something that they're gonna freak out about, and I'm just so excited for them to watch it and love me more."

Meanwhile, Rihanna - Billie's Smurfs co-star - is also delighted that her kids can now finally enjoy the movie.

The chart-topping singer - who has RZA, three, and Riot, 23 months, with A$AP Rocky - recently told Extra: "We get to watch the movie together for the first time. I get to watch it in its full completion. So, that should be interesting.

"Everybody gets to watch it on the 18th. So, we're really going for it now. It's finally being birthed."

Rihanna explained that the film's premiere felt "so far away" when the project began.

She said: "We've been working on it for so long. So, like, a few years now, actually. And it's happening … You know, you start working on something and 2025 feels so far away and then we're here."

Rihanna's sons weren't aware of her involvement with the movie.

However, the singer - who has largely put her music career on hold in recent years, in order to focus on other ventures - was looking forward to seeing the reaction of her boys.

Asked if they knew that she was playing Smurfette in the film, Rihanna replied: "The boys know nothing, they're being introduced to Smurf Village right now, the blue carpet, and next is going to be me watching their reaction when they realise my voice is coming out of the screen. I can't wait for that one."
