MUMBAI: Singer Katy Perry and actor Ryan Phillippe were reportedly flirting and giggling at singer Elton Johns 70th birthday party.

"She was totally giggling and at one point he had his hand on her knee. Then he took off but came back late with for more flirting," the source added.

Perry and Phillippe were joined by Neil Patrick Harris, Jon Hamm, James Corden and Heidi Klum at the star-studded party on March 25.

The news about them flirting comes as a shock because Perry was reportedly thinking about rekindling romance with her former beau John Mayer.

"She's told him she still loves him, but she's still very hesitant to give him another chance. She's afraid of getting hurt by him again," a source said.
