New York: John Mayer rang in his 35th birthday with an all-day, all-night birthday fete with on-again off-again girlfriend Katy Perry in New York City.

The couple started their date with an intimate late lunch at ABC Kitchen in the West Village, the New York Post reported.

A witness inside the Jean-Georges Vongerichten restaurant told the publication that the couple looked romantic.

“They were holding hands throughout the meal and they definitely looked like a full-on couple,” a source said.

Mayer and the 27-year-old singer were later spotted having a dinner at Freeman’s in the Lower East Side.

After dinner, the couple went to burlesque club The Box and didn’t go home until 4 am.

For the occasion, Perry donned a floral dress while Mayer was dressed in a jean jacket and dapper bow tie.

While their couple status is yet to be confirmed, Perry has reportedly fallen “head over heels” and “dangerously in love” with the crooner.
