Pitching in on promotional efforts for her upcoming comedy "The To Do List," Rachel Bilson paid a visit to the set of "Chelsea Lately" last night (July 25).

While discussing the film, the "Jumper" beauty dished to Chelsea Handler about the 1990's wardrobe she wore.

"It was fun. We got to wear all the clothes from the '90s and the set dressing and all that. I guess I'm a clothes whore from the original '90210' costumer closet," Miss Bilson explained.

The well-known comedian then asked, "Really? Whose clothes were you wearing? Tori [Spelling's]?"

Referring to the Tori's character, Rachel answered, "Probably Donna Martin's. I don't know how I feel about because I was definitely a Kelly girl [Jennie Garth's character]. But I had Donna Martin on. That sounds really weird. But I did."

"The To Do List" hit theaters today (July 26). For more on the funny interview, check out the video below!
