hot seat.

The Oscar winner will be deposed in a $25 million defamation lawsuit over his 2013 blockbuster Wolf of Wall Street, a Long Island federal-court judge ruled Thursday.

TheNew York Postreports DiCaprio, who earned an Academy Award nomination for best actor for his role as sleazy businessman Jordan Belfort in the flick, is set to be grilled by lawyers for Andrew Greene, a former colleague of Belfort’s.

Greene sued Paramount Pictures and others in 2014 claiming the flick portrayed him in the movie as a toupee-wearing, prostitute-loving degenerate character named Nicky “Rugrat” Koskoff.
