Washington, June 9 : Uma Thurman has for the first time opened up about how much she misses her late friend Natasha Richardson, who lost her life in a freak skiing incident earlier this year.

In an interview with Harper''s Bazaar U. K., the `Kill Bill' star said that she missed being a "passenger" on Richardson''s driven life.

"She (Natasha) would have a plan on arrival anywhere and would be carving the best out of life and every situation and every person," Fox News quoted Thurman as telling the magazine.

She added: "She wasn't as much a passenger as I am, which made us great companions in life . because every driver needs a passenger . and every passenger needs a driver. So it's a big loss in my life."

Richardson''s sudden death has inspired Thurman to make sure she lives her life to its fullest.

The 39-year-old actress, who was married to and shares two children with actor Ethan Hawke, is all set for a London wedding to British tycoon/philanthropist Arki Busson.

Thurman said: "Isn't life amazing? Isn't life full of surprises? When it comes to things like marriage, you just never know. I find that growing up has been all about realizing that life gets more serious, and that it's also really important to increase your sense of humour." (ANI)
