Happy Halloween 2012, Rihanna Announced On Twitter $100,000 Party

Rihanna sent a "Happy Holloween" message to all her Twitter followers on Wednesday and reports state that the singer is planning a huge holiday party tonight that will cost roughly $100,000 or more - one that will not include Chris Brown's ex-girlfriend Karrueche Tran. 

A source told Hollywoodlife.com, ''Even though Ri cool with what's going on [between the three of them] I ain't sure if she trying to have KT all up in her party. And KT don't want to go. Ri's crew don't like her. KT should keep her a** at home.''

The love triange between the two singers and Tran started when Brown was still in a relationship with the model and starting to rekindle his "friendship" with Rihanna. Even though Brown has been seen getting cozy with Rihanna, he was also spotted having dinner with Tran in West Hollywood, Calif., on Oct. 26, before attending together the opening of a new store. 

Rihanna's Halloween party will reportedly have more than 300 guests and the "Diamonds" singer will pay for an open bar, according to the National Ledger.
