Danniella Westbrook has criticised This Morning, alleging the programme 'dropped' her from a guest slot on Tuesday.
The former EastEnders actress claimed she was due to appear to talk about her health but got an email from a producer saying her interview had been cancelled.
According to the Celebrity Big Brother star, the email said that there were "concerns around her wellbeing" and mentioned how Danniella had pulled out of a scheduled appearance on Loose Women the year before.
Sharing the message with her 233k Twitter followers, an outraged Danniella wrote: "So @ITV @thismorning ask me on the show to talk about my health and what I've been through this last year then pull it! Trying to make me look bad!"
She added: "Using @loosewomen as an excuse I was still miscarrying when I didn't do Loose Women that day! It's a joke the way they've used me."
Guest appearances are often subject to change on a daily live programme.
A spokesperson for This Morning told ED! "Guest appearances are often subject to change on a daily live programme."
Danniella, 44, has since deleted her tweets hitting out at the show, and pinned another where she says she needs to get away from it all on holiday.
She wrote: "Time to go on holiday I think so can't deal with this weather and people's negativity in my industry right now... I need sunshine and smiles not dark clouds and sky snakes in my life."
Danniella's agent told ED! of the matter: "We cannot comment at this time".
The mystery over her This Morning appearance comes as the mother-of-two has had a well-publicised and difficult year. She pulled out of an appearance on Loose Women in September - and it was later revealed it was because she had tragically suffered a miscarriage.

Danniella explained to The Sun : "I haven't been well and when I got to Loose Women this morning, I spoke to the producer and told him that I'm still bleeding a little bit and he got a medic to come in and see me.
"He said that in medical terms I don't think it's fair if we put you on live TV."
Around the same time, she also split up from her partner Alan Thomason, 34, following allegations they'd had a huge bust-up in a Benidorm hotel room.
Danniella has spoken out in the past about having a drug addiction in her youth, and has been open about her mental health.
She rose to fame playing Sam Mitchell in EastEnders in the nineties and later reappeared for short stints in 2009 and 2016.
