A new book on Lady Gaga claims the award-winning singer is petrified of being alone and would often insist that her former assistant, Angela Ciemny, share her bed.

“We would do our make-up together every morning and get ready for bed together at night,” Ciemny says in the book Poker Face: the Rise and Rise of Lady Gaga.

Ciemny says that when she would try to head back to her own room, the singer would throw a fit, insisting she stay.

“Gaga couldn’t sleep without someone next to her in bed,” according to the book.
