Madonna's grilling!

Look who's jumping on the latest trend.

Madonna sported a shiny grill (and a Joker smile) Wednesday as she paid a visit to her Hard Candy Fitness center in Rome. Earlier this month, Rihanna showed off her shiny gun-shaped tooth bling. And Beyoncé jumped on the bandwagon, giving the trend a try, too.

Wearing a black minidress, black tights and her signature fingerless gloves, Madonna made a quick inspection of the facility, reports the Daily Mail.

The singer has been in a celebratory mood lately. Son Rocco turned 13 and the star celebrated with a game of paintball.

And Madonna celebrated her own birthday on Aug. 16, when she turned 55. She marked the occasion with a lavish French Revolution-themed party.
