John Mayer and Kat Stickler are SO a thing! They just took a huge step in their romance! As we've been following, the 48-year-old musician has been sparking romance rumors with the 31-year-old influencer (though she's insisted she's single as a pringle). But this weekend's sightings would suggest otherwise! The couple was spotted at Torrisi, an Italian restaurant in New York City, on Saturday, according to several eyewitnesses who spilled the tea to DeuxMoi.
