Lady Gaga dominated the 30th BRITs on Tuesday, winning a trio of awards at the pop music industry’s flagship ceremony, the first international act to do so for five years.

Gaga, dressed in a ghostly carnival headdress and skimpy lace outfit, picked up awards for International Female Solo Artist, International Breakthrough Act and Best International Album for “The Fame,” winning every category in which she was nominated.

The singer, on top of the music charts for most of the last 12 months, dedicated an eerie live performance to fashion designer Alexander McQueen, who died last week.

“Thank you so much for believing in me,” she told her fans.
