Reese Witherspoon: I Don't Know How to Keep Quiet!

Reese Witherspoon (in Rebecca Taylor) grabs a cup of coffee and chats with a gal pal at a Starbucks in Santa Monica on Thursday.

The mother-of-two wore a pair of black oval shades, a black sheath dress and strappy Christian Louboutin slingbacks. She also toted around the Chloe Bay bag. Reese, 31, just topped People’s Best Dressed List for her “The Celeb Next Door” style.

When asked at the Toronto Film Festival why she decided to open up to Elle Magazine about the after-math of her marriage with Ryan Phillippe, she said, “I guess I don’t know how to keep quiet!”

Don’t keep quiet about your relationship with Jake Gyllenhaal then!
