Which Hollywood ladies have fallen for John?
Even celebs wear the same outfit twice! Katy Perry was spotted re-wearing a Chanel tracksuit that she originally wore after a long flight with ex-husband Russell Brand back in April of 2011.

The “Fireworks” singer was in the tan sweat suit with similar brown ballet flats on Thursday in New York City, when she was seen leaving on-again boyfriend John Mayer’s apartment.

What have the love birds been up to in NYC?

The 27-year-old singer has made a habit out of wearing her trusty ensemble for long flights from New York or London back to her hometown of Los Angeles.

Her recent trip to the Big Apple has been jam-packed with birthday festivities for her soulful crooner boyfriend. Mayer, who turned 35 on Oct. 16.

They celebrated his birthday with a lunch at Manhattan’s trendy ABC Kitchen followed by dinner at Freeman’s in the Lower East Side.

The two musicians carried on their late evening with drinks at NoHo’s Acme and then dancing at burlesque nightclub The Box.

“There wasn’t a cake or anything special for him, because they didn’t want to draw any attention to themselves,” an eyewitness exclusively told Celebuzzof their time at The Box. “They were only really talking to one another. They were really cute together.”

The couple has been ramping up their romance throughout their New York trip, officially cementing their blossoming relationship.

Since announcing her divorce from funnyman Brand, 37, in December 2011, Perry has been linked to male model Baptiste Giabiconi and Florence + The Machine guitarist Rob Ackroyd.
