Alison Pill opened up about her topless photo scandal roughly a year ago – when she accidentally uploaded a nude picture of herself onto her Twitter profile – while visiting Conan Tuesday night.

When host Conan O’Brien admitted to being nonplussed about how exactly the accident transpired, Pill gamely explained the incident. “It's a fascinating story involving not knowing that my new BlackBerry had a touch screen,” Pill said. “And responding to somebody on Twitter like, 'Oh yeah, New York was great, it's 9:30 on a Wednesday, also, apropos of nothing, here are my boobs!'"

Pill also revealed why the racy image was on her phone in the first place. “I had been away from my, at the time, fiancé and we had spoken on the phone the night previous . . .," she told O’Brien, declining to go into further detail about the exchange with actor Jay Baruchel, whom she split from earlier this year.

At the time, Baruchel joined in on the laughs regarding Pill’s accidental exposure. “My fiancee is a hilarious dork," the She’s Out of Your League actor, tweeted. "I'm just glad it didn't happen to me first. Smartphones will get ya. CC Alison Pill. Viva Ludditism."

While Baruchel may have found it amusing, Pill was mortified. "I realize just how dumb and so embarrassing," she said. "So hideously embarrassing that for about three months after it happened… anytime I met a new person I [kept thinking], 'Boobs! Nice to meet you, you've seen my boobs.'"

Pill currently stars in HBO’s politically-tinged drama The Newsroom, which will wrap up its sophomore season on Sunday, Sept. 15. The series, which also stars Jeff Daniels and Olivia Munn, was recently renewed for a third season.
