Reese Witherspoon legs skirt yellow hat cute sunglasses smile necklace beverly hills

It's a sunshiny day!

Arriving at her office in Beverly Hills, Reese Witherspoon enjoyed the Los Angeles weather in her sunny yellow sweater and miniskirt on Monday.

Showing off the fruits her workout labor, the 38-year-old was in a particularly good mood when she flaunted her lean legs in a black and white print miniskirt.

The mom-of-three was keeping her fair skin out of the sun with a wide-brimmed hat and some cool shades.

The bubbly blonde has been hitting both yoga and Burn 60 in Brentwood on the reg for the past few months. We aren't sure if it's because she is exercising for a role in one of her upcoming films, or if she just got inspired after pics of her bum were splashed all over the Internet when photogs caught the Oscar winner accidentally flashing her backside last June. Clearly her gym routine is paying off!

Reese's highly anticipated film, The Devil's Knot, finally hits theaters on May 9. The film is based on the true story of three teenagers who were falsely convicted of killing two 8-year-old boys in Tennessee. The trio, known as the West Memphis 3, were released two years ago after spending 18 years behind bars. Reese plays Pam Hobbs, the mother of victim Stevie Branch, and Colin Firth also stars in the movie as Ronald Lax, a private investigator who represented one of the accused teens.
