You may think Beyonce is being PETTY - but she wanted to celebrate her 35th birthday WITHOUT two people who she doesn't care for.
MediaTakeOut.com spoke with MULTIPLE PEOPLE who attended Beyonce's star-studded 35th birthday party in Manhattan yesterday, and they all agreed that Kim Kardashian and Rihanna were NOT there - and they were NOT INVITED.
One insider explained, "Beyonce doesn't like Rihanna, and Rihanna doesn't like Bey. [Beyonce] believes that Rihanna was with Jay Z, and she'll never forgive her for that."
And as for Kim, well it's a little more subtle. The insider explained, "Kim would try and take over the party, and Snapchat everything. Nobody needs that. The party was supposed to be low-key and for friends only. Kim ain't her friend."
Since BOTH Rihanna and Kim were in New York last night, there was SOME CONCERN that the ladies may try and CRASH the party. We're told that SECURITY AT THE FRONT DOOR was told to NOT ALLOW either woman into the venue if they arrived.
