According to a source, the pop star bought her “Telephone" collaborator a custom-made leather diamond-studded whip.
Gaga also treated Beyonce to an a capella rendition of "Happy Birthday" backstage at Jay-Z's concert with Eminem in Detroit, Michigan last week. A source tells Britain's The Sun, "Gaga wanted to give her something special. The whip was made out of hundreds of diamonds and leather."
"When Beyonce received it she squealed with excitement. The dressing room was decorated with balloons and banners and a lot of champagne had been put on too."
Gaga reportedly dropped thousands on the gift.
We wonder what Jay-Z was thinking when he saw the whip?
