Allen has retreated to her English countryside home to grieve for her loss, and Britain's Mail on Sunday columnist Katie Nicholl claimed that she and boyfriend Sam Cooper were set to walk down the aisle in the New Year (11) after "they realized through their grief that they absolutely adore one another and cannot live without each other".
But an angry Allen has taken aim at the writer on Twitter.com, launching a foul-mouthed tirade against Nicholl.
On her page, she writes, "Katie Nicholl you're a lying c**t, leave me out of your s**tty column, you know nothing.
"I'm sorry, but there's a time and a place for disrespectful, badly researched or just made up journalism. It's not now Katie Nicholl."
