Always keeping things interesting, Lady Gaga was in party mode as she partook in the first day of the 2010 Lollapalooza Festival in Chicago, Illinois on Friday (August 6).
Held in Grant Park, the "Alejandro" singer surprised her many fans as she stepped out in a see-through bodysuit to go crowd surfing at the BMI stage as Semi-Precious Weapons performed.
As for her night-ending set, Gaga treated the crowd to an energetic show while speaking to the crowd much more than has been usual during her never-ending Monster Ball tour.
Among the highlights, the 24-year-old became quite emotional before a version of “Speechless,” during which she praised her father for being her inspiration - telling a story about how he "kicked off her music career by helping her carry her piano up a long staircase at their New York apartment when she was a kid."
