Lady Gaga was groped by a fan outside her hotel in Paris on Monday (December 20).
The singer was leaving the hotel in the French capital when a girl grabbed her right breast.
Lady Gaga's minders were forced to step in to remove the fan's hand, according to The Sun.
The singer is in Paris to play two rescheduled gigs at Bercy, which were originally due to take place in October.
But she was forced to postpone the first date on Sunday (December 19) when her touring party was impounded outside Paris.
The gig will now take place tonight (December 21).
