Adrian Grenier made sure that this Halloween was equal opportunity scandalous with his costume over the weekend. See, girls aren't the only ones who take it as a night to dress slutty! Ha. I suppose he was dressed as a wrestler while his lady friend was...mostly naked. Thankfully for all of us, his friends the paparazzi were there to capture his daring outfit. Ari Gold would be proud of his, uh....gutsiness.
