Someone's in a good mood!

On Friday afternoon Reese Witherspoon stopped by the hair salon in Beverly Hills, and the 38-year-old Oscar winner smiled sweetly as photographers snapped away. She's not usually super chatty with us, but she always gives good face. And those legs! It's like she hasn't aged one bit since her Legally Blonde days...

And speaking of Reese in the movies, earlier this week it was confirmed that the actress and Nicole Kidman’s production companies (Pacific Standard and Blossom Films, respectively) are teaming up to option the film rights to Big Little Lies by Liane Moriarty. The novel is a dark comedy about several Australian mothers whose kids all attend the same kindergarten. And when we say dark, we mean dark -- it's a murder mystery!

Deadline reports that Kidman and Witherspoon will star in the movie.
