Chris Brown and Karrueche have been tied together in one romantic way or another since his second split with Rihanna, and he was recently seen leaving a party with her on October 18th, kissing as they made their exit.  According to a source who claims to be close with Chris and Karrueche who spoke with Hollywoodlife.com, the young pair are no more than friends with benefits at this time.

"I mean, they're friends with benefits and have been for a long time now. Yeah, they kiss but that's PG compared what they do behind closed doors.  That's what they do and nobody should be surprised. They had a good time at the party. They left together and did what they did and that's it. He likes her but he's not about to be in a committed relationship with anybody.  They both like s**t just the way it is. They're friends with benefits and it works.

"He's straightforward and honest with Karrueche, For years, he thought he always had to lie to females and sneak around. But a wise man told him if he's always honest, s**t always works out for the best and females respect that. Since he's been doing that, his life has been carefree."
