Michelle Pfeiffer is nursing an ugly black eye after an accident on the pickleball court.

The actress warned her Instagram followers of the dangers of the sport, showing off her injury in a series of photos. 

"WARNING," she wrote. "Pickeball-Stay out of the kitchen!! Thank you, Less!" 

The "kitchen" is the area on either side of the net where players are not allowed to volley the ball. It is unclear how Pfeiffer was injured.
