Here are some photos of Katy Perry at Comedy Central’s “Night Of Too Many Stars” benefit for autism where she performed on Saturday evening. I’ve been unable to unearth a designer ID on this sheer gown, but it doesn’t really matter because Katy is still doing her misguided goth impression. Honestly, the hair here is too severe, and the flat black color makes her look much older than her 27 years. Furthermore, I never cease to be amazed at the amount of foundation (also quite aging) she piles on her rather pretty face. Too much, Katy. Too much.

Now onto the latest news in the Katy Perry and John Mayer bad romance, which has seen its ups and downs after first losing traction in late August when they broke up after two months of douchery and being the perfectly gross couple. Then in early September, the two surfaced together again but tried to seem lowkey, but we knew they were totally still doing it. Then last week, Radar Online reported that Katy had enough of John’s crap and told him “lose my number,” but I guess that didn’t happen because now they’re being all disgusting together in NYC where they were spotted on a dinner date together. And to make matters even more icky, John was feeding Katy with his fork:

These two really aren’t shy about showing off some PDA.

When Katy Perry and John Mayer went for a romantic date at Perla in NYC on Oct. 14, they were so loved up that he was feeding her!

“They came in around 9 p.m. with another guy and girl. During appetizers, Katy used her fork and her hands to eat off her and the others’ plates and John fed her with his fork!” the eyewitness tells Life & Style. “For the main course, the table shared a few dishes. And dieting seemed to be the furthest thing from Katy’s mind! She was eating large sums of pasta.”

“Katy and John sat across from one another,” adds the eyewitness. “They seemed relaxed and comfortable. Katy was over-the-moon happy … and laughing a lot. John was just as happy. They were really flirty. They kept leaning into each other over the table to talk and barely checked their phones.”

Katy and her female friend made sure to document the special night.

“When they came back from the bathroom, they asked their waitress to snap a photo of the group,” the eyewitness says. “They left a little after 10:30 p.m.”

After finishing up at the restaurant, they headed to private club Soho House in the Big Apple’s Meatpacking District, where they were spotted playing pool around midnight.

Earlier that evening, John, 34, supported Katy, 27, at her private concert at the Best Buy Theater.

“He was in the VIP area next to the stage on her right,” an eyewitness tells Life & Style. “He wasn’t singing along but he was clapping after each song and nodding his head to the music.”

And the night before, the pair were spotted sharing a smooch at Hotel Chantelle.

“John met Katy at the hotel and they sat at a table near the DJ booth the whole night, looking happy,” a guest at the hotel tells Life & Style. “They were kissing each other every now and then and left together at the end of the night.”

What is up with this recent need for celebrity couples to feed each other in public? Ashton Kutcher was recently spotted feeding gelato to Mila Kunis, and the trend is still as yucky as when Cameron Diaz was caught feeding A-Rod some popcorn at the SuperBowl. Do people really do this? I just can’t imagine feeding anyone who can feed themselves.

Here are some photos of John sneaking out the back door The Troubador in LA on 9/28. He’s definitely not one of those people who are fortunate enough to have a “hat head.”
