Bacardi and Maroon 5 hosted a Halloween Party where all sorts of celebrities got together for good times and good music. I’ll tell you what, Adam Levine makes a pretty convincing John McClaine. The rest of the band dressed up as Nikolai Tesla (Jesse Carmichael), Bono (James Valentine) and The Boy With The Red Balloon (Michael Madden). Other guests included Rose McGowan as Marie Antoinette and Austin Nichols and Sophia Bush as Russell Brand and Katy Perry, respectively. You can check out more photos after the jump.
