Just how twisted are twin sisters Mary-Kate and Ashley Olsen?

Who wudda thunk it?

THE WORLD IS HER ASHTRAY

Litter bug Ashley Olsen tosses her cigarette onto the ground after taking a few puffs while out and about in Los Angeles over the weekend.

Thanks to Celebrity Babylon, there’s now photographic proof that the 21-year-old million dollar baby doesn’t care much for Mother Earth!

Mmm, yummy cancer sticks.

The Olsen Twins go the great white way at the Seventh on Sale dinner gala at NYC’s 69th Regiment Armory on Thursday. Ashley kept in classy in Calvin Klein Collection while Mary-Kate went leggy in Giambattista Valli.

Seventh on Sale is basically the world’s largest sample sale. Scores of fashion brands have donated thousands of items to be sold through December 7 on 7thonsale.ebay.com. 100% of the money raised goes to services and housing for those living with HIV and AIDS.

It looks like Mary-Kate opted to wear designer Giambattista Valli’s “The Victoria Shoe” as inspired by Victoria Beckham.

Ashley Olsen, 21, and cycling champion Lance Armstrong, 36, are the latest odd couple to surface in Hollywood, reports Page Six.

The couple showed up to the Rose Bar at the Gramercy Park Hotel Monday and spent the night together.

One bar spy said, “They came together with a group of friends. Ashley drank red wine, sat on his lap and they were making out all night. They left together around 2 a.m.”

This is one rumor I wouldn’t mind being shot down by one of their publicists!

Ashley was at one point romantically linked to 30-year-old club owner Scott Sartiano. Seems like she’s climbing up the age ladder of men!
