Decked out in all-black athleisurewear, a fresh-faced Rinna paired plain leggings with a loose-fitting long-sleeved top and face mask. Opting for a pop of color on her feet, she went with lime-green sneakers.
Despite her recent affinity for wigs, Lisa's hair was in its natural shaggy state with what looked like fresh highlights blowing in the wind.
Rinna and her crossbody Gucci bag made their way into a pizza joint in West Hollywood, California. She emerged soon after with a medium-sized pizza box and small white bag likely containing other goodies.
It's the first time the Bravo star has broken cover since she put Kathy on blast for spending last weekend rubbing elbows with former President Donald Trump at his Mar-a-Lago Super Bowl party instead of in Beverly Hills filming the Season 12 finale with the rest of the cast.
"Oh that's where she was!!!!!" Rinna captioned an image showing Hilton posing and smiling for pictures at the big event.
It's apparent Lisa did not not buy the reason Kathy's team gave Radar for her finale absence.
Her manager previously told us that she and her husband, Rick Hilton, had always planned on being in Palm Beach last weekend, which Bravo apparently knew about well in advance.
However, no mention of Trump or Mar-a-Lago was made during our chat. Instead, Kathy's manager told us she was traveling to Florida to visit a friend who was celebrating the one-year-anniversary of her husband's death and that she also had plans to co-host a charity event with her daughter, Nicky.
Hilton's manager told us that the last time she filmed was last Thursday and seemed to insinuate that she and Rinna did not leave off on good terms. Shortly after, a well-placed source confirmed that the two were feuding.
As we reported, Kathy is upset that information about a meltdown she had while on the cast trip to Aspen, Colorado, got leaked.
The insider told us that it was Erika Jayne who allegedly bore witness to the freakout and claimed to hear Hilton use foul language, which Jayne then allegedly told Rinna about. Lisa was then allegedly keen on backing up Erika's story.
Since then, Rinna's been alluding to having received a cease and desist; however, Kathy's team denied to us that it was from her.
