Katy Perry and John Mayer Together at Four Seasons

After being spotted going out on a date last week, pop singer Katy Perry and acoustic crooner John Mayer both hit up the ritzy Four Seasons Hotel in L.A. over the weekend, heating up rumors of a potential romance between the two musicians.

It all started back in June when Perry and Mayer were seen together on a supposed pizza date. Later, on July 19, the duo reportedly met up at West Hollywood's Soho House. Sources say that they were "affectionate and cuddling." 

The "Teenage Dream" singer Perry was seen walking into the Four Seasons with a gift in her hand over the weekend, and not long after she stepped foot into the hotel, it was confirmed that Mayer had already arrived a few minutes earlier.

A few days before this Mayer and Perry were spotted together in a car, enjoying a night out on the town with dinner at the popular Pace Restaurant and then partying at the celeb hotspot the Chateau Marmont Hotel. Check out some pics of the two hanging out in the car here.

While Perry has finally settled her divorce from the "Forgetting Sarah Marshall" funny guy Russell Brand, Mayer currently has a running record with flattering A-list female celebs, from Jennifer Aniston to Taylor Swift to Minka Kelly.

But both singers are single and ready to mingle, so there's a good chance that fans will see more of these hotel date encounters in the near future.
