Diddy toasted his favorite Bad Girl’s 26th birthday at a private celebration over the weekend.  The hip-hop mogul invited some friends and family to his Los Angeles crib for an intimate soirée.  Cassie partied with Diddy’s son Justin Combs, French Montana, Kevin Hart, and fellow Virgos Evan Ross and Keke Palmer, who were both celebrating their birthdays.

She played ping-pong in her stilettos and guests gathered around to sing “Happy Birthday” to her.  Diddy even presented the “King of Hearts” singer with a gold Rolex to match his.

“Happy Birthday @casandrae @cassiesuper…Had to match dem Rolexs baby…Team us! Let’s Go!” he tweeted.
