Simpson and Mayer dating again?

Jessica Simpson and John Mayer were spotted at the posh Four Seasons Hotel in Beverly Hills, California on Monday night, just weeks after their brief relationship reportedly ended.

Mayer was staying at the hotel and chatting up various women in the bar, when Simpson arrived and met up with old friend and producer Romeo Antonio, who has written several songs for her.

According to entertainment news website TMZ.com, when Antonio excused himself to go to the men's room, Mayer followed him and asked whether there was anything romantic going on between him and Simpson.

Antonio said there was not.

Mayer then went back to the bar and spoke with Simpson for 10 minutes before the pair exited together and took the elevator upstairs to Mayer's room.

The couple were romantically linked last month after Simpson appeared on the cover of American publication People with the headline: "I'm In Love," referring to her reported relationship with Mayer.
