Are these songbirds be turning into lovebirds?

Katy Perry and John Mayer were — again — spotted out and about in Los Angeles Saturday night. The duo hit a house party in the Los Feliz, Calif., neighborhood before driving away in Mayer’s car.

Though the couple were recently enjoyed a dinner-for-two at the Chateau Marmont together, a Celebuzz source say that the meeting was strictly all business.

 “It wasn’t a date. They met up about a potential music collaboration,” a source told us.

The once outspoken Mayer, 34, has kept out of the public eye since dating Jennifer Aniston in 2009.

Meanwhile, Perry, 27, has recently finalized her divorce from divorce from British comedian Russell Brand.

“Katy is toying with the idea of working with John,” the source adds.

“But whether or not they work together remains to be seen.”
