*Demi Moore, 47, got her bump and grind on for all to see at a Snoop Dogg concert in Las Vegas over the weekend.

According to the footage on YouTube and paparazzi snaps, the actress and her husband, Ashton Kutcher, were at some point invited on stage.  The “Punk’d” king chose to stand and watch as his cougar gyrated and coochie-popped around like a “video vixen.”   Click here to watch.

Snoop made a surprise appearance at the second annual Brooklyn Loves Michael Jackson event in New York on Sunday to mark the late King of Pop’s 52nd birthday.

The rapper joined in the festivities at Brooklyn’s Prospect Park, an event organized by Spike Lee, and treated the crowd to a special performance of his hits, remixed with a variety of famous Jackson tunes.

The event also featured a set from rapper Warren G, while civil rights leader Reverend Al Sharpton led a minute’s silence for the late superstar, as well as the victims of Hurricane Katrina, which struck New Orleans, Louisiana five years ago.
