Reese Witherspoon raised eyebrows when she made a snippy remark about naked pictures during her acceptance speech at the MTV Movie Awards on Sunday, but a rep for the actress denies the joke was a jab at Blake Lively, who was the victim of an alleged nude photo leak last week.

While accepting the MTV Generation Award the Oscar winner quipped, "If you take naked pictures of yourself on your cell phone, you hide your face, people! Hide your face!"  So what did her publicist have to say about the purported attack on the 23-year-old Gossip Girl star?  "Reese was absolutely not referencing Blake Lively," Witherspoon's rep told Us Weekly on Monday.

Last Tuesday several websites posted nude cell phone pictures of what appeared to be Lively in front of her bathroom mirror, but her rep shot down the rumors, insisting that the photos were "100% FAKE."  In case you missed it, check out the video of Reese's rant below!
