ET set up on the red carpet last night for the premiere of the action-comedy This Means War starring Tom Hardy, Chris Bane, Chelsea Handler, as well as Reese Witherspoon, whom her co-stars gushed about.

When television host Chelsea Handler was asked about what it was like working with Witherspoon, she explained that it was loads of fun.

“We had the best time together,” Handler said. “She’s professional but I’m not, so it was fun for her to be like, ‘What the hell am I supposed to do with this basket case?'”

Chris Pine, who plays one of the men who is dating Witherspoon’s character in War, revealed his warm thoughts on the 35-year-old actress.

“She’s beautiful and she’s smart. She’s witty,” Pine fawned. “I fell in love with her the first time I sat down across from her.”

Upon her interview with ET, we saw exactly why Witherspoon’s co-stars were so fond of her. Despite a very successful acting career, the Louisiana native remains very down-to-earth and warm-hearted.

This Means War, featuring the lovely Reese Witherspoon, comes to theaters on Valentines Day (Tues., Feb. 14).
