Gaga: I just wanted to crowd-surf
Lady Gaga has explained her crowd-surfing antics, saying she hadn't planned it and just got caught up in the moment.
The Poker Face star jumped on stage with support band Semi Precious Weapons at the Lollapalooza festival before she leapt off and decided to crowd-surf.
"I was so excited because I haven't crowd-surfed in a long time because no one lets me any more, I don't know what came over me - I just got so excited and I remember playing that stage and what it felt like and they were doing such a great job... I just jumped," she told Ryan Seacrest on his radio show.
Lady Gaga - real name Stefani Germanotta - has been busy writing music for her next album.
"[My album] kind of is done, but I can't stop writing music. I don't know what I'm going to do. I might have to put out two records," she said.
"When I put this album together, I wanted to write the album in an innovative way. I want the message to be innovative. I already have the sonic ideas and the message ideas."
