The stars got into the same car as they exited the restaurant
New year, old flame?
“They were both with a group of friends. Not together or anything flirty or love interest-type,” an onlooker tells PEOPLE.
Mayer, 38, kept to his signature look, wearing a dark coat, while Perry, 31, brightened things up in a white dress with a colorful design.
“They got a table together about 10 of them in total and went straight there after John’s show,” the onlooker says.
Perry and Mayer reunited just in time to spend the New Year together.
The two singers continue to leave fans scratching their heads over their relationship status. They first started dating in 2012 and have been on and off ever since.
“John and Katy looked happy,” a source told PEOPLE at the time. “They held hands and sat next to each other during the wedding ceremony.”
They were also seen together over the summer, attending the Grateful Dead farewell concert series in Chicago.
