Star lena dunham showing off her girls. I never see you naked, you always see me naked. Reporter: But when a tv critic asked her about her frequent nudity at a press conference on thursday, an all-out war of words ensued. Dunham telling him, it's a realistic expression of what it's like the be alive. If you're not into me, that's your problem. This morning, malloy is speaking out. I thought that was a big artistic choice. I was inquiring why she made that choice. Reporter: Jenny said dunham was in a rage spiral saying he accused her of showing her body too much. I never criticized her appearance and would never. It would be crazy and tasest and awful. Reporter: It's not the first time critics spoke up. Last season, her character had a weekend affair with patrick wellsen. Claiming the tryst between the mismatched pair was implausible and uncomfortable and that same no holds bard attitude was on display at the golden globes. Right here, honey. What is the most girly thing about you? My genitals. Reporter: As for her spat with malloy, she's not responded for comment.
