Kyle Richards and her rumored girlfriend Morgan Wade attended her sister Kathy Hilton's Christmas party in Bel-Air on Saturday, where they celebrated the holidays with Tiffany Haddish, Kate Beckinsale, Paris Hilton and Nicky Hilton Rothschild.
Richards, 54, and Wade, 29, were seen in a series of images posed with fellow partygoers, marking the Bravo star's first holiday season since revealing she and estranged husband Mauricio Umansky had separated in July.
At Hilton's party, Richards was clad in a shoulderless red satin dress with a bow across the chest, with a sparkly gold purse and open-toe beige heels. She wore her dark locks styled to the side in front and wore hoop earrings at the luxe gathering.
Wade, a country music artist, was clad in a patterned black jacket over a silk button-up plum top with black pants and black shoes. She wore her hair down and parted.
Richards and Wade - whose relationship has been a focal point on The Real Housewives of Beverly Hills this season, posed together in photos with Kathy, Paris and Haddish in front of the massive decorated Christmas tree in the home.

Kathy, 64, hosted a previous holiday party at the home last month that Kyle attended, as well as their sister Kim, 59.
On Monday, Kyle shared with her 4.2 million Instagram followers a series of party shots, as well as other weekend festivities, in a carousel set to Brenda Lee's Rockin' Around The Christmas Tree.
'Such a beautiful weekend surrounded by family & friends,' she captioned the montage of photos.
TMZ reported in July that Kyle had been 'dating country singer' Wade in the wake of her separation, and that they 'allegedly have matching heart tattoos.'
In August, Richards appeared as Wade's love interest in the music video for her track Fall in Love with Me, in which they were seen in a bubble bath and nearly kissing.
Richards and Umansky issued a statement on Instagram July 3 in which they denied getting divorced, but didn't deny separating.
It read: 'In regards to the news that came out about us today… Any claims regarding us divorcing are untrue. However, yes, we have had a rough year. The most challenging one of our marriage. But we both love and respect each other tremendously. There has been no wrongdoing on anyone’s part.'
They continued: 'Although we are in the public eye, we ask to be able to work through our issues privately. While it might be entertaining to speculate, please do not create false stories to fit a further salacious narrative.'
