Perry didn't appreciate the gesture and asked friends to keep Lohan away from her because she was acting "weird", The Sun reports.

"Lindsay followed Katy around trying to take a photo with her. Katy told her friends to keep her away as she was acting really weird," a source said.

The party was thrown by Perry for her stylist Johnny Wujek in California a couple of weeks ago.

Lohan recently held a slumber party with Lady GaGa and Lana Del Rey at the infamous Chateau Marmont hotel.

Perry is rumoured to be dating John Mayer.
