John Mayer & Katy Perry: Birthday Night in the Big Apple
The “No Such Thing” stud wore a denim jacket with a white shirt and a black bowtie as he escorted the vintage floral dress-clad “Firework” songstress to the Box Nightclub.
Earlier in the day, John and Katy treated themselves to a late lunch at the ABC Kitchen eatery where they weren’t shy about their public displays of affection.
An eyewitness told press, "It was hard to recognize them because Katy had a hat on that was covering her face. But she and John were alone, they were holding hands throughout the meal and they definitely looked like a full-on couple."
