Beyoncé — along with her mom, Tina Knowles, and guests including Kim Kardashian — attended a karaoke bash thrown by jeweler Lorraine Schwartz and her sister Ofira Sandberg at LA hot spot Blind Dragon this week.
“Beyoncé was dancing on a couch while her mom did a rendition of Chaka Khan’s ‘I Feel for You,’ ” said a spy.
We’re told other singers included DJ Cassidy — who took the stage to perform Nelly’s “Hot in Herre,” only to be joined by the rapper himself. Tiffany Haddish grabbed the mike to sing “Proud Mary,” and the evening ended with Schwartz and Sandberg belting out Mariah Carey’s “All I Want for Christmas Is You” — which we’re told had Beyoncé and other party guests dancing and singing along.
