Lady Gaga gifts diamond-studded whip to Beyonce

London: Pop star Lady Gaga has reportedly gifted R&B singer Beyonce Knowles a custom-made diamond whip and matching underwear set for her 29th birthday.

The `Poker Face` hitmaker splashed out thousands of dollars on the raunchy gifts, which she presented to her while singing `Happy Birthday`, reported Sun online. "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," said a source. Gaga handed over the saucy gifts backstage at Beyonce`s husband Jay-Z`s concert in Detroit last week, with the rapper also making an effort to celebrate his spouse`s birthday. "The dressing room was decorated with balloons and banners and a lot of champagne had been put on too," said the source. Gaga`s eccentric present is apparently inspired from her prison-themed music video for single `Telephone` which starred Beyonce. The duo dressed in sexy leather and studded outfits for the shoot, with Gaga wearing metal chains and Beyonce sporting a tight black jumpsuit and chauffeur`s hat. PTI
