The 'Marry the Night' hitmaker was so delighted to hear her UK 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 UK 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 UK. 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."
