Reese Witherspoon finds Sofia Vergara one of the funniest people she's ever met

Actress Reese Witherspoon has compared her upcoming untitled comedy film to 1991 classic “Thelma & Louise”.

The 38-year-old, who will play an uptight policewoman who finds herself on the run with a drug dealer's wife (played by Sofía Vergara) in the film, says that her co-star is one of the funniest people she has ever met.

Speaking at Sean Penn's annual pre-Golden Globes benefit for Haiti relief organisation J/P HRO, Witherspoon said: "It's (the film is) definitely like a 'Thelma & Louise' kind of thing.”

Talking about Vergara, she added: “She is one of the funniest people I have ever met in my entire life. But working with her I could literally not stop laughing. I think people are going to love her in this movie.”

Witherspoon has also said that Vergara has worn “really hot clothes” in the film, and added: “She looks adorable. She's beautiful, she's funny -- everything that you know she is you get to see her for two hours on a movie screen,” Witherspoon added.
