Gaga's YouTube account suspended
Lady Gaga had her account on YouTube temporarily suspended.
A notice said the suspension was due to "multiple or severe violations of YouTube's copyright policy".
By late Thursday, the Poker Face singer's account had been restored.
Google-owned YouTube declined to comment. It is YouTube policy to remove accounts after three copyright violations - although they can be restored after being corrected.
Reports have suggested that the infringing video was a recently uploaded clip of Lady Gaga's performance on Fuji TV.
The singer's publicist and record label were not available for comment.
The account is one of two for Lady Gaga.
The removed channel is run by Gaga's camp, while she also has an unaffected Vevo account. That account, which has more than 1.6 billion views, generally debuts her music videos.
