The Don't Hold Your Breath singer, who has previously been supported by Gaga on a past Pussycat Dolls tour, is a big fan of the pop superstar.
Scherzinger, 32, told Attitude magazine: 'We were one of her very first tours. I am a huge fan. I just love her style and her vibe and her energy. I could tell that she was an artist, even when she didn't have a big production or the money.'
She added: 'When she was just lying on the floor with a hand-made fairy cane stick or whatever and light-up glasses, I thought, 'She is a monster in the most wonderful, beautiful way.''
