Inside Kathy Hiltons’ holiday bash: Paris sings her 2006 single, dad Rick performs a Rolling Stones classic

Kathy Hilton pulled out all the stops at her annual holiday party this year.

The Hilton family matriarch and “The Real Housewives of Beverly Hills” star, 65, hosted the festive bash at her home in Bel-Air, Calif., with Christmas carolers and her own family providing the entertainment.

Her hubby Rick, 69, surprised guests with a karaoke rendition of the Rolling Stones’ “Sympathy For The Devil” — and while he needed no introduction, the hotel heir belted out the lyric, “Please allow me to introduce myself!” a partygoer told Page Six.

Guests laughed and cheered him on, we’re told.

And Kathy joined in and rocked out with an air guitar.

Meanwhile, the couple’s famed eldest daughter, Paris Hilton, 43, didn’t need karaoke, but relied on her own pop hit to get the crowd going.

“Paris hit the dance floor, getting the party moving with a nostalgic singalong of her [2006 song] ‘Stars Are Blind,’” our source said.

Paris and her husband, Carter Reum, brought their son, Phoenix, and daughter, London, who celebrated her 1st birthday last month.

Other guests at the festive bash included Heidi Klum, Demi Lovato, Joan Collins, Jaime King, Rachel Zoe, Jennifer Tilly, Bozoma Saint John and longtime Hilton family friend, Nikki Haskell.

Kathy partnered with UrbanStems for her floral decor, and supplied guests with her signature POMtinis.

Guests lso went home with pieces from her Kathy Hilton x Anna Zuckerman jewelry collection, we’re told.
