Lena Dunham has taken to Twitter to respond to claims that she sexually abused her sister as a child.

The 'Girls' actress recently came under fire by right-wing conservatives who have argued that Dunham herself described molesting her younger sister Grace in her new memoir, 'Not That Kind of Girl.'

Indeed, Dunham shared several passages in her memoir in which she remembers, at seven years old, masturbating in bed beside her young sister and once curiously touching her, Truth Revolt reports. Dunham also seemingly compares herself to a "sexual predator," writing:

"Three pieces of candy if I could kiss her on the lips for five seconds. Whatever she wanted to watch on TV if she would just 'relax on me,'" Dunham writes in the memoir (see the full passage here). "Basically, anything a sexual predator would do to woo a small suburban girl I was trying."

However, as sites like Truth Revolt have attacked Dunham, seeing these memories as sexual abuse instead of a young child's curiosity, the HBO star has lashed out on Twitter, writing:

"The right wing news story that I molested my little sister isn't just LOL- it's really f---ing upsetting and disgusting," Dunham shared.

"Usually this is stuff I can ignore but don't demean sufferers, don't twist my words, back the f--- up bros," she continued.
