Lindsay Lohan's alcohol-monitoring bracelet began flashing "furiously" while she was at a party in Los Angeles, it has been claimed.
The troubled Mean Girls star was at pal Katy Perry's bash after the MTV Movie Awards. And although she didn't appear to be drinking, the court-ordered device lit up, it is claimed.
One source said: "All of a sudden, it started flashing furiously - bright red, fast flashes. She wasn't drinking or doing drugs that I saw. She didn't seem fazed whatsoever. I mean, it was very obvious. She was just hanging out, and acting like it was totally fine."
Lohan, 23, was last month ordered to wear the anklet after she failed to turn up at probation hearings related to her drink-driving and drug arrests.
