Showbiz correspondent and former 'Strictly' contestant Richard Arnold was chatting to Susanna and her co-host Ben Shepherd when a parp sound could be clearly heard.
Cue Susanna being reduced to a giggling mess and Richard protesting that "it wasn't me" but actually the 'GMB' sofa that had made the noise.
Hmmm, that old chestnut, Richard (watch the video above and decide for yourselves).
Just last month Susanna had former 'Downton Abbey' star Dan Stevens in hysterics with a badly worded question on the ITV breakfast show.
The 43-year-old presenter was interviewing Dan about his latest action flick, 'The Guest', when she enquired if he had to 'beat off a lot of men' to land the role.
