Chris Brown and Karrueche Tran at GreyStone Manor Halloween Party

Chris Brown attended the same Halloween party on Sunday night as Karrueche Tran – prompting reports that he has got back together with his ex.

Chris Brown, 23, and Karrueche reportedly ended their relationship earlier this month, with rumors suggesting that he has rekindled his relationship with music superstar Rihanna.

However, Rihanna will be less than happy when she discovers that Chris Brown and Karrueche Tran both attended the GreyStone Manor Halloween Party together.

Chris Brown and Karrueche Tran arrived and left in separate vehicles during the horror themed event, which saw Brown dress up in a baseball top and ghoulish white and black make-up.

Karrueche Tran wore an Oriental style dress as she partied with revellers.

Chris Brown looked to be in high spirits on the night, and certainly has been struck by Halloween fever.

On Saturday, Chris Brown was spotted at a Halloween themed party at the Playboy mansion.

While he never dressed up that night, he made some effort for Sunday’s night bash – and pulled a series of creepy faces as he attended the party.

Despite the partygoing atmosphere, Karrueche Tran was seen almost constantly on the phone.
