Katy Perry and John Mayer are definitely feeling the love.
The pair was described as "super affectionate and loving with one another" while out to dinner at New York eatery The Lion Saturday night, toasting Girls star Allison Williams's boyfriend, CollegeHumor.com founder Ricky Van Veen. The actress hosted a small, intimate bash for her beau, who was celebrating his birthday that night.
Following dinner, the group was treated to a surprise magic act, then spent the rest of the night playing games and savoring desserts before leaving at 2 a.m.
According to an onlooker, Mayer was "very gracious, charming and kind" throughout the evening. – Kristin Boehm
Frightful but delightful!
Katy Perry joined a group of girlfriends Sunday for a night out at the Los Angeles Haunted Hayride.
Before embarking on a private hayride, Perry and crew met up with Fashion Police host George Kotsiopoulos and his friends.

"Katy was in there for about 30 minutes!" an onlooker tells PEOPLE. "She seemed to be having a ton of fun and shared lots of laughs with her friends."
"She loved being scared by all of the characters each time they snuck up on her!" the source adds.

Katy Perry was a social butterfly on a recent night out at Soho House in West Hollywood.
Wearing a white lace dress, the pop star ran into a table of business associates having dinner in the garden and stopped to catch up before heading inside to the bustling bar to meet up with friends.
The recently single singer "was all smiles and in great spirits," an onlooker tells PEOPLE. "She had hellos for everyone at the table. She was adorable and spoke to them in a character-like cutesy voice before making her exit about five minutes later."
Things were calm for Tom Hardy, who was also at the Soho House the same Wednesday evening.
The Dark Knight Rises actor was spotted "having a nice time with a small group of friends around the bar area," an onlooker says. "He was chatting away and listening to stories while he sipped on a cocktail."
"He looked like he was enjoying a very low-key night out," the source adds.

There's no slowing down for Katy Perry.
One night after supporting musical pal Ferras during his performance on Thursday at Bootsy Bellows in West Hollywood, the single "Teenage Dream" singer lent a hand to another friend.
Perry planned a special birthday party on Friday night for her close pal Jon, who is Ronan Farrow's – the son of Woody Allen and Mia Farrow – best friend.
Renting out all of SHOREbar in Santa Monica, Calif., Perry was joined by approximately 40 guests, including Ronan, Hilary Duff and husband Mike Comrie, Ferras and the venue's owner John Terzian.
"At the stroke of midnight, Katy brought out a birthday cake that had Jon's face on it, and she sung 'Happy Birthday'," a source tells PEOPLE. "She was in good spirits, laughing and seeming to enjoy the night."
Guests at the intimate fete sipped from the bar's signature punch bowls, while listening to tunes spun by DJ beeFOWL.
Perry stayed until around 2 a.m., but "wasn't being a party animal," the source adds.

Are Katy Perry and John Mayer wild for each other – or are they just having a good time hanging with wild animals?
The duo attended a weekend bash at Hollywood talent agent Michael Kives's house, where they were greeted by several special guests: animals from a conservation (including an alligator and a kangaroo!).
"They were really cute," an attendee tells PEOPLE. "They were standing near each other most of the night, playing with the animals outside."
When they weren't checking out the nonhuman partygoers, Perry, 27, and Mayer, 34, "definitely enjoyed each other's company."
Katy Perry is used to being the one on stage, but on Monday night, she was able to relax to the sounds of a live act other than her own.
The "Teenage Dream" singer took in a show by British indie pop band The xx, who hadn't performed in the U.S. in two-and-a-half years.
Perry, in a large bohemian-style black hat and a floor-length floral dress, hung toward the back of the Fonda Theatre in L.A., where the show was held.
"As her bra strap slid off of her left shoulder, a smiling Katy began to dance around to the band's hit, 'VCR,' " a source tells PEOPLE. "She was with a crew of pals, including her assistant and a few guy friends."
Katy Perry's fans were in for a big surprise on Wednesday night when they attended a screening for the pop star's Paramount documentary, Katy Perry: Part of Me.
Clad in a red floral dress with an open back, the "Wide Awake" singer popped up at the theater inside The Grove in Los Angeles just as the lights went down for the viewing to begin.
Once Perry arrived, she told the crowd, "You guys are all so cute, even all the way to the back," an onlooker tells PEOPLE.
"Little girls rushed the screen as Katy walked around slapping hands and greeting fans," the source says. "She managed to sign some autographs and pose for a few pictures before trying to disperse the massive crowd that had gathered around her."
Perry, who said a few more sweet things to her admirers on the mic, "was all smiles and seemed genuinely excited for her young fans to see the film," the insider says, adding, "The start of the screening was delayed a good 10-15 minutes before Katy sat down in the middle of the screaming crowd for a bit."

Katy Perry seemed to be in quite an upbeat mood on Saturday night when she made her way to Club Robertson's Rasputin night in West Hollywood.
Right across the street from local celebrity favorite spot The Abbey, the "Part of Me" singer didn't go incognito as entered the venue with her purple hair capping off a red dress .
"The DJ announced a little after midnight that she was there," a club-goer tells PEOPLE. "She partied at a booth with a bunch of males who definitely appeared to be just friends. She had some kind of beverage in her hand."
Standing on a banquette at one point, the source says Perry "danced to Britney Spears' s hit '...Baby One More Time.'
"Katy was in a roped-off area, but she was still accessible to her fans," the source adds. "She was posing for photos with people at the club and seemed to be having a great time." That's for sure: that night, the singer quoted Spice Girls on Twitter, writing, "If you wanna be my lover you gotta get with my friends. #fact."
Once it was announced that Perry was on the premises, the source says, "The line got super long and it was really hard for people to get in."
