Amid 'American Idol' rumors, Steven Tyler parties hard in Las Vegas

Is someone starting the celebration a little early?

Steven Tyler is reportedly in final talks to join the judges panel of "American Idol," but he clearly wasn't thinking about contracts during a July 31 Vegas after-party at Studio 54 following an Areosmith show earlier in the night.

And as if one show during the night wasn't enough, the 62-year-old rocker spent much of the night leaning over the railing of the club's skybox, at one point belting out an impromptu rendition of "Walk This Way."

On his arm was girlfriend Erin Brady, who preened in front of cameras in a white dress when the couple walked the red carpet outside the venue. Later, she looked on as Tyler signed multiple partygoers' cleavages.
