(NGRE/AKM-GSI)

Things are heating up for singers Katy Perry and John Mayer.

The pair was spotted leaving a Los Feliz house party Saturday night and getting into Mayer's car. The singers kept it casual with Perry opting for a red, flowered sundress and Mayer dressed down in a white button up and jeans.

The pair sparked dating rumors Aug. 1 when they were seen leaving celebrity hotspot, Chateau Marmont, also in Los Angeles, where they reportedly had a dinner date.

Could Mayer be a rebound for Perry? After 14 months together, the "I Kissed a Girl" singer and actor Russell Brand filed for divorce in December. Since the divorce, Perry has been linked to male model Baptiste Giabiconi and Florence And The Machine guitarist Rob Ackroyd.

As for Mayer, he has been linked to a long list of Hollywood starlets including Jessica Simpson, Jennifer Aniston and Taylor Swift.
