Los Angeles, March 11 (IANS): Actress-writer Lena Dunham has apologised for tweeting a joke about molestation.

The 27-year-old, who regularly strips off for scenes in her hit TV series "Girls" , appeared on US chat show “Saturday Night Live” over the weekend, and mocked her penchant for nudity by shedding her clothes in a skit about biblical figures Adam and Eve, reports contactmusic.com.

A sketch that she made during the show irked some viewers, with one taking to Twitter to tell the actress: "You don't always have to get naked", to which Dunham quipped: "Please tell that to my uncle, mister. He's been making me!"

The star later deleted the post and apologised for the remark, posting: "I just made and deleted a not so great molestation joke. Sorry guys. I am really sleepy. Snl (Saturday Night Live) has a way bigger audience than our usual cozy 'Girls' audience, so I was seeing a rash of very different kinds of Twitter rage.

"But I should know better, and do. Even naked girls get embarrassed. Sleep well and thanks for an amazing weekend."
