Katy Perry's SPOOK-tacular Birthday Party With John Mayer…AND Kristen Stewart?!

| Filed under: Love LineJohn MayerParty Poppin'Katy PerryKristen StewartHalloween


Sorry, Donald! Guess she didn't take your advice!

Katy Perry will turn 28 this Thursday, and celebrated her upcoming birthday over the weekend by combining some of her favorite things this month: Halloween spookiness and her on-and-off man, John Mayer!

The pop star had a MASSIVE costume party Friday evening at The Magic Castle in El Lay, during which she dressed up as a very SEKSI Vampire, while her man for the moment opted for some Zombie hunting threads!

And guess who else showed up for the festivities?!

Kristen Stewart, who apparently decided to leave Robert Pattinson at home for the night while she pAArtied with friends!

A source reveals:

“She looked happy and was surrounded by her friends the whole time.”

As you can see from the photo (above), it certainly looks that way!

But she couldn't even be bothered to dress up?

Hey! Maybe she went as a sullen hipster or something! LOLz!

Regardless, it looks as though Miz Perry had a night full of SPOOKS, SCARES, and delicious cake (as seen below), so we couldn't be more thrilled that everything seemed to be so enjoyable for her!

Happy happy to YOU, gurl!

    so she's a vampire wearing 100 crosses…
    does anyone else understand that? Because I'm confused.

  2. 2

    I find John more attractive like this. Makes me realize how soft his real features are - this is much more masculine.

    Re: CaritaDeCleopatra – I noticed that too.

    Pr low or somethunny how all the pics show up and names of guest in attendance along with it on another sight so soon, what they trying to show us? That theya they needy for attention. All they are doing is making people sick of them. As for crosses, be lucky she didn't wear them upside down like she does her rin

    Re: unknown – . Sitting here tapping my finger on keyboard, waiting for john to come along and correct the spelling and punctuations, hahaha

    Why dump on Kristen Stewart? She doen't appear to be the only guest, who did not wear a costume.

    Maybe they think they are much to grown to play dress up. Some people are really mature like that.

  7. xyz says – reply to this


    Re: mm – I would assume that if a person is a actress, she plays dress up enough, and wants to feel normal.

    First of al check info before printing, Rob is in Australia promoting BD2.
    Second kristen is friends with Katy and she was with her/robs friend Marcus foster at the party, and bobby was there to. And some of Kristen's own friends to.
    Third Kristen look super cute in her glasses =)

  10. meg says – reply to this


    Well Rob wasn't there as he flew out of town on Friday for the upcoming press tour for BD2.

    Re: lorelore – Kristen has plenty of money to go around all dolled up and grab the attention but she doesn't. Get off her back.

    john mayer went as his ugly inner self.

  13. Not Fascinated says – reply to this


    Boring group. Not intrigued. What's new? Mayer is trying to capture his wonder years by hanging with the 20 something's. Not cool or witty. His youth has faded. He will be hanging at high schools, pulling girls from graduation next. It's always weird to see celebs at costume parties because most of them live in makeup and costumes anyways, so changing clothing really doesn't awe me…………

    Re: Not Fascinated – Hahaha! NO ONE cares if you are awed. LOL!

  15. Oh yeah, right....NOT! says – reply to this


    Re: Not Fascinated – He's so not trying to capture his wonder years. He wants a match to share his life with. Is that so bad? I think no. I honestly wish them the very best.

  16. teeter totter says – reply to this


    Sounds like fun, always wanted to go see the magicians, but do not know any members.

    Probably something I will not get to do in this lifetime, maybe next if there is one and I am good.

    I wish them the best.

  17. ME says – reply to this


    Re: Oh yeah, right….NOT! – totally agree. I wish them the best and think they are a totally amazing well matched couple. She is a beautiful woman.

  18. I love Katy & John! says – reply to this


    They are incredible & utterly fantastic together. One hot couple. Holy creativity. I send them lots of love.

  19. Sandra says – reply to this


    I'm much happier to read positive comments that show maturity especially in the case of KStew. There is enough negativity in this world without people being so judgemental and mean about everything. Lets stop and hope that love wins afterall

  20. Emma says – reply to this


    Jesus Perez, what's with your hard on for hating Kristen Stewart There are obviously other people not dressed up…Plus your ridiculous insinuations about her sleeping with obviously gay men (Taylor Lautner) and a man she's probably never met (Justin Theroux). She's been publicly dogged on for months…I thought you were trying to be a little kinder, too?

  21. 21

    Oh man that is so spooky because that is probably what John Mayer looks like in real life and only Grimms can see his true self.

  22. Priya says – reply to this


    Re: Emma – You're no better than Perez or any other bully, for calling Taylor Lautner gay when you have no proof! Until the guy says so, which he hasn't, get off his case.

    I bet Katy and John had some wild and crazy sex if they wore those Halloween costumes to bed. Katy biting his neck with her fangs and John kissing all over her with that freaky redneck zombie killer face and outfit on. It must have been one of her more memorable birthdays she's ever had. Katy seems to have a "goth" side to her sometimes so probably loved it.

  24. ELECTRIC says – reply to this


    Ok this couple blows Brad Pitt and Jennifer Aniston (remember people considered them the "Golden couple" or Pam Anderson and Tommy Lee away. (Sorry but they were sexy together and it was love.)
    John & KATY are like John Lennon and Yoko Ono or Elizabeth Taylor & Richard Burton….EPIC!!!
    God I love these two together.They belong together. Brilliant, electric, beautiful, thoughtful, creative and kind. BESOS!
