Katy Perry flirts with Pattinson
Katy Perry - who is dating Russell Brand - amazed onlookers at a Californian nightspot by flirting with Robert Pattinson
Katy Perry and Robert Pattinson spent the night flirting with each other at a mutual friend's birthday party.
The 'I Kissed A Girl' singer - who is dating comedian Russell Brand - and the 'Twilight' hunk were at Dimples Supper Club in Burbank, California, and onlookers say they "only had eyes for each other".
Website Radar Online says the pair: "Sat face-to-face, touching foreheads and acting very flirty with each other. They were both giggling and Katy looked positively giddy!"
It is not the first time Katy and Robert - who has an on/off romance with his 'Twilight' co-star Kristen Stewart - have been to the karaoke venue together.
A staff member said: "They came here last year and every time she comes he seems to follow."
Although she seemed quite smitten with Robert, Katy did manage to find time to take to the microphone.
She belted out a Christmas track on the karaoke machine and when she and her friends took to the stage for the last song of the night, they weren't impressed with the DJ's choice of Pink's 'So What'.
She started shouting: "Wrong song! No! We don't like Pink."
However, her pleas were ignored and she eventually gave up and she and her friends sang along.
At the end of the evening, Katy, Robert and a friend all left for home in the singer's Audi.
