Vanessa Feltz stunned the This Morning host's today wit her outrageous sex noises.
The agony aunt loudly faked an orgasm live on air during a phone-in on nightmare neighbours.
Holly Willoughby was screaming while co-host Phillip Schofield was left in stitches as he struggled to continue with the show.
Viewer Jade wanted her new neighbours to stop making love really loudly in earshot of their 15-year-old.
She said: "My new neighbours are really loud when making love. It's awful. We hear them downstairs in the front room and their bedroom joins onto theirs. We don't want our 15-year-old hearing her. What do you think should we do?"

Vanessa admitted she couldn't go round and ask them for a timetable of their sexual activities.
She asked: "How long are they lasting. Are these marathon sessions of incredibly loud gasping?"
Vanessa then suggested that the best solution would be just trying to ignore it, which left Holly shouting: "Oh no."
When Vanessa started speaking about how loud and what they were yelling, Holly cried: "I can't think about this anymore."
Vanessa then claimed Jade could set up a competition to try and one up her neighbours.
She said: "As soon as you hear them doing it tell you 15-year-old to go out and start doing what they're doing but louder. See how they like it.
"Makes some noises," she said before leaning back and looking upwards while shouting: "Yes, yes, yes."
Giggling Holly said: "Or just record that and play that back."
Phillip Schofield said it was time for a break but couldn't stop laughing as he tried to reveal what was coming up next.
As the show went to the ads, Phil burst out laughing and slammed his hands down on the desk.
