Lena Dunham has cancelled two dates of her European book tour following recent allegations that she "molested" her younger sister.
The author tweeted to confirm she was cancelling two events in Berlin and Belgium as part of her book tour to promote her memoir Not That Kind of Girl.
Dunham's decision to cancel the dates follows her furious reaction after a right-wing website in the US claimed she "sexually abused" her younger sister.
The article published on the blog Truth Revolt cites a passage from Dunham's memoir in which she talks about seeing her younger sister's vagina at the age of seven.
It claims the Girls creator describes using her sister to sexually experiment with, writing that she attempted to persuade her to kiss her using the sort of methods "a sexual predator might do".
Dunham posted a series of angry tweets addressing the allegations made in the article.
"The right wing news story that I molested my little sister isn't just LOL- it's really f**king upsetting and disgusting.
"And by the way, if you were a little kid and never looked at another little kid's vagina, well, congrats to you.
"Usually this is stuff I can ignore but don't demean sufferers, don't twist my words, back the f*** up bros.
"I told a story about being a weird 7 year old. I bet you have some too, old men, that I'd rather not hear. And yes, this is a rage spiral. (sic)"
A representative for Dunham has yet to confirm whether the author has plans to cancel any more dates on the European leg of her tour.
