Lady Gaga Works Up A Sweat On Her Birthday

When you've got millions in the bank, and you're one of the world's biggest stars like Lady Gaga, you could do pretty much anything for your birthday so how did the pop star celebrate her 26th birthday? By heading to a spin class.

The 'Marry The Night' singer celebrated her birth in Hollywood by having a private spin class party at SoulCycle.

According to a source, Gaga even requested songs to get her burn going. "She requested [Bruce Springsteen's] 'Thunder Road' because it's one of her favorite songs," a source told Us Weekly. "Her friends filled the studio, and they had a blast."

Gaga even shunned LA's celeb haunts for dinner, but instead just had a homemade dinner with her parents.

"It was just a small thing with her family," the source added. "Her mother cooked."

The friend revealed that Gaga's hectic schedule meant that she was really keen to keep it a low-key affair.

"She's been ridiculously busy, and has been working herself very, very hard," they said. "But everyone had the most amazing time [yesterday]!"
