Thandie Newton Loves Matthew Williamson

Thandie Newton gets more and more beautiful with age!

The British actress attended the the Matthew Williamson “10 Years in Fashion Gala” with the designer himself at the Design Museum on Tuesday in London.

Thandie, 34, is currently shooting the Guy Ritchie-directed film RocknRolla. She plays an “accountant who becomes more and more crooked as the story goes on.”

“I think [Guy] was surprised at how dirty I played this character. I just kept pushing it and he loved it,” she giggled. “He loves surprises.”
