Last night, Donatella rocked out to the "Just Dance" singer during her concert in Milan at Mediolanum Forum.
The fashion designer often makes sure Gaga is decked out in her Italian label and Mother Monster has been all about Versace during her current Joanne World Tour.
When Gaga landed in Italy this week, she was able to lay her weary head on some super expensive Versace bedding compliments of her bestie. Versace even made a custom printed, sparkly unitard for the singer to wear at her Milan show.
In December, Gaga rocked a vintage Versace suit from the 1992 Spring/Summer collection.
Um, we'd like to go shopping in Versace's old closet!
