Katie, 36, hasn't held back when discussing her bedroom antics with her past flames, including Alex Reid and Leandro Penna, and it has left her sibling Danny embarrassed.
Danny is currently running Katie's Twitter account while she is in the CBB house, and last night (22 January) he made no secret about how awkward he is feeling.
"No more sex talk please - we're British #cbbkatieprice," he tweeted...to her two million followers.
Earlier in the week, as Katie spoke in detail about ex-husband Alex Reid's passion for anal sex, Danny also told her fans: "Well that was an interesting one....very educational....I'm off to research 'can the blackhole really be filled....?'"
He then added: "I am @g00dshepherd and I will be having nightmares tonight." Oh dear!
Meanwhile, last night Katie told her housemate Michelle Visage that she was worried about all the saucy things she has been saying on the Channel 5 reality show.
Katie admitted she fears she will get a bad reaction from the public when she leaves, adding: "I can't help it!"
Following her frank admissions, both Alex and Leandro have responded. Cage fighter Alex said he was "disappointed" that Katie had felt the need to discuss their personal life, while Argentinian model Leandro attempted to rise above it with a series of cryptic tweets.
