Lady Gaga buys driver a year's supply of diapers

Gaga has treated her chauffeur to a year's supply of diapers.

The 'Marry the Night' hitmaker was so delighted to hear her U.K. driver was about to become a dad for the first time that she splashed out on the practical gift for him.

A source told The Sun newspaper: "Gaga is very generous with her presents and makes a huge effort for those who look after her. As soon as she found out her U.K. driver was going to be a dad, she was on the phone, trying to sort out a gift. It had to be something quirky, too - it's part of her nature.

"Gaga has used the same driver for years since she first started performing in the U.K.. The poor guy has to drive her through hordes of screaming fans after gigs. Considering how often she stands up through the sunroof to salute her Little Monsters, he must know every inch of her midriff."

Gaga will be swapping Christmas presents with her 'Vampire Diaries' boyfriend Taylor Kinney, when he flies from Pennsylvania to New York on Boxing Day on December 26 to spend time with the singer and her parents.

The couple have been dating since meeting on the set of her 'You and I' video earlier this year.
