Rob and Kristen spotted at a Maroon 5 Halloween party last night - From Maroon 5's twitter- Maroon 5 will host their own personal spooky spectacular Halloween party on Oct 31, from 8 pm to 2 am at the Hollywood Forever Cemetery.
From the looks of it RK went with their friends. Katy Perry and Justin Bieber were also there. Someone mentioned a party bus.... do they mean Bieber's party bus?? LOL I'd give anything to see Kristen on that party bus. haha
