TMZ obtained this photo of Mr. Tirade himself, walking into one of Sin City's hottest clubs, PURE at Caesars Palace. Sources inside tell us that Gibson headed up to the VIP stage and had the shades drawn. Now that's ballin'! Mel was also peeped on Tuesday while checkin' the scene at another top-notch club, JET at the Mirage.
Mel sipped on Red Bull and water most of the time -- good thing for him, because he still has to appear at a DUI progress report in February.
We've also heard that Mel Gibson partied at Blush in the Wynn Hotel. Our spies tell us he had a private table and was spotted dancing with Eddie Murphy's ex-wife Nicole. Nice!
