Yolanda Foster and daughter Bella Hadid, in a new Instagram post, matched in red one-piece swimsuits poolside at the reality star's stunning Southern California home.
The 18-year-old wrote Sunday, "Mommy n meee day," with an emoticon of a sun to go along with the shot, in which they're posed back-to-back with matching pouty expressions.
"Home is when I'm with you my angel ... heart, shown in emoticons," the model added.
The Real Housewives of Beverly Hills star has leaned on her three children -- also daughter Gigi and son Anwar -- during her grueling three-year Lyme Disease battle. (The tight-knit family has shown they're not only close with their mother, but one another: Earlier in the weekend, Bella posted a shot with her stunning siblings, writing, "I'm like a mix of my jaguar brother and snow leopard sister.")
As RadarOnline.com previously reported, Foster's health battle has been a source of animosity for some of her Bravo castmates after returning Taylor Armstong "was openly questioning how sick Yolanda was" during a cast get-together, angering Lisa Rinna.
"Taylor said she was having major doubts about how serious the Lyme disease was for Yolanda, who wasn't at the party," sources told Radar, adding that "Rinna was openly seething with anger because Taylor doesn't even know Yolanda, and shouldn't have even gone there!"
