REAL Housewives of Beverly Hills star Lisa Rinna has left her friends and family gobsmacked after posing nude for a new photoshoot.

The 56-year-old shared the pictures on Instagram, and the comments came flooding in, with daughters Amelia and Delilah in shock.

"WAIT WHAT," wrote Amelia, before in a second comment adding: "WHEN DID YOU DO THIS."

In a third comment she shared: "YOU ARE HOT."

Her sister Delilah also couldn't believe what was seeing on social media, writing: "Mom, when tf did you do this?"

Lisa's husband Harry Hamlin also chimed in, praising his wife and writing: "That's my girl!"

Celebrities including Jenna Dewan and January Jones also posted comments that featured fire emojis, while Lisa's co-stars Dorit Kinsley, Erika Jayne and Kyle Richards had nothing but adoration.

Dorit shared: "Damn this is next level," as Kyle joked that Lisa should "wear this to the reunion."

Things have been heating up between the Real Housewives stars in recent months, in particular between Lisa and Kyle, and Denise Richards.

In early June, fans saw Denise still upset about the “threesome” conversation that occurred within earshot of her daughters, Sami, 15, and Lola, 14, at a previous party.

While on a girls' weekend Lisa shocked Denise asking her: “Do you talk about the hookers around your kids?

"About the hookers that Charlie brings around?

"Because you've been quite free with us.”

"Privately, yes, I’ve had private conversations with them,” Denise responded appearing shocked.

Denise said in a confessional: “Wow! This is my friend of 20 years, she knows I've protected these kids all these years.

“I don't know if she's trying to embarrass me or humiliate me. I don't know. I don't know what her agenda is, but whatever it is, it's f**king hurtful. Really hurtful."

Denise has yet to comment on Lisa's picture.
