Scheana Shay has slammed Lisa Vanderpump for joking about Kristen Doute's pregnancy.

The 39-year-old TV star has hit out at Lisa, 64, after she recently joked about the paternity of Kristen's unborn child on the 'Housewives Nightcap' podcast.

Scheana said on the 'Scheananigans' podcast: "One thing was the host brought up Kristen's exciting pregnancy news and Lisa's response was, 'Do we know who the dad is?'"

Scheana was surprised and disappointed by Lisa's recent comments, even though they were clearly intended as a joke.

The reality TV star actually called Lisa's remarks "unprofessional".

Scheana said: "I just want to say - with all due respect - it was kind of shady."

Scheana - who was an original cast member on 'Vanderpump Rules' - can't understand why Lisa decided to make a quip about Kristen's pregnancy.

She explained: "Like you know who Luke [Broderick] is. You know he's a cast member on this show.

"This season, they get engaged. And if you don't know who someone is on a show that you're producing, then why is your name in the credits as a producer?"

Lisa hasn't spoken to Kristen - who announced her pregnancy in November - since 2020, when she was fired from 'Vanderpump Rules'.

Kristen now stars on 'The Valley', the 'Vanderpump Rules' spin-off show, and Lisa serves as a producer on the series, even though she's "not very involved" with the program.

Lisa said on the 'Housewives Nightcap' podcast earlier this month: "I hadn't heard that [Kristen is pregnant].

"How on Earth did that happen? Who's the father? Do we know?

"Oh, she's getting married? I'm really not very involved in 'The Valley' even though I'm a producer."
