After sitting next to Lindsay Lohan at a private birthday party Masha Markova‘s $11,000 fur coat disappeared — only to reappear on the pages of OK Magazine being worn by LiLo!

According to the New York Post, the 22- year-old Markova flipped when she saw her MIA fur in the mag.  She surfed the net and spotted her coat again in paparazzi pix of the boozy blonde.

Club owners vowed to get to the bottom of this fur-ensic mystery.

Results were not forthcoming.

That’s when Masha’s attorney, Merrill Cohen got Lilo’s litigator, Blair Berke on the hot line. 

Hours later, Markova got a call from the club 10ak and the coat arrived at her apartment the next day.

The once pristine mink reeked of cigs and booze and a slight tear of the lining in the priceless gift from her grandmother.

"I don’t see how it could have been an accident," Markova said.
