Katy Perry, John Mayer & Rihanna's N.Y.C. Night: Dinner, Drinks & Instagram!
The trio caught up at West Village hotspot The Lion on Monday night
After a busy day – the singer’s single "Roar" hit the Internet – Perry caught up with friends at the bar before heading upstairs to a private room for dinner.
“Katy and John were adorable,” an onlooker tells PEOPLE. “Katy introduced him to people as her boyfriend and John affectionately held her close with his arm around her.”
Just as the 15 guests were finishing their entrees, Perry’s pal Rihanna arrived.
The “Diamonds” singer sat next to Perry and Mayer and the trio caught up. Rihanna even posted a snapshot with Perry on Instagram, writing “She. X She. #KatyAnna #RIHunited”
