The actress talked about her recent autobiographical book, which exposes a childhood which she describes as 'straight out of The Sopranos'.
But it was the mother-of-two's seemingly confused behaviour which caused onlookers to describe it as a 'Kerry Katona moment'.
'What on earth was wrong with Patsy Kensit on @itvthismorning today?' said one shocked viewer.
Another added: 'What is up with patsy kensit on @itvthismorning ?! She's doing a Kerry katona.'
'What is up with patsy kensit on @itvthismorning?'
Some tweeters even asked whether Patsy was drunk, but many jumped to her defence, explaining that it could be the medication she is taking against menopausaul symptoms such as the sweats and a dry mouth.
Presenter Holly Willoughby looked concerned, as Phillip Schofield asked:
'You've been very poorly and you've documented that in the book so our final question is: 'How are you Patsy?'
Speaking honestly, Kensit responded:
'I had to have a hysterectomy two months ago. I was getting these huge cysts I had one removed in 2011 and within nine months two huge cysts had come back.
'Now I'm going through full blown menopause. My mouth is dry, I have the sweats.'
'No one talks about it. It's somehow taboo like you're not a woman any more. Do you lose your lust for life because you've lost your womb?
'I would have loved to have someone to call, 45 is quite young (to have a hysterectomy).
'I'm feeling okay, but it's a big adjustment,' Patsy concluded.
Speaking about her failed marriages to rock stars Jim Kerr and Liam Gallagher, the Holby City actress admitted:
'I'm feeling okay, but it's a big adjustment'
'It really saddens me to have failed so miserably with my boys' dads'.
'We were young and I believe in love and I'm a hopeless romantic and that's nothing to be ashamed of.
'I have learnt so much from Jim and from Liam and I was looking for them to replace my mother's love and no man can do that.'
Before quickly adding: 'Maybe you can Phillip.'
