Danniella Westbrook claims the producers of "This Morning" tried to make her look bad by cancelling her planned appearance on the show.
The former "EastEnders" actress was set to star on the programme, but in a series of now-deleted tweets, Danniella claims the producers were using a cancelled appearance on "Loose Women" last year as "an excuse".
Danniella - who has struggled with drug addiction - wrote on the micro-blogging website: "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!
"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. (sic)"
The actress also shared a screenshot of what appears to be part of an email from a "This Morning" producer informing her of the change of plan.
Later, Danniella revealed on her Twitter account that she's now facing legal action.
She wrote: "Now have legal action being taken for standing up for myself !!! # This industry really (sic)"
Danniella then revealed she plans to go on holiday in order to escape the stresses of the TV business.
She said: "Time to go on holiday I think [thinking emoji] 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 (sic)"
Meanwhile, a spokesperson for ITV told Digital Spy: "Guest appearances are often subject to change on a daily live programme."
