Lena Dunham revealed that she felt "chubby" and short while standing on stage next to Taylor SwiftLily AldridgeGigi Hadid and Hailee Steinfeld at Swift's concert in New Jersey on Friday.

"I was so thrilled to support my friend and so displeased to learn about the truth of my own height," Dunham told Judd Apatow while speaking with him at a talk hosted by Film Society of Lincoln Center on Monday. "I've been feeling pretty tall, feeling pretty sturdy, and it was amazing to me, like, 'Oh, I'm not tall, I'm chubby.' It's different."

She said that she's usually very secure about her body, but this was a unique incident.

"I mean, on most days, I feel really great and fine about my body, but I don't think standing next to, like, three supermodels or so is anything even the most confident woman needs to do."

She added, "The minute I caught sight of myself on the Jumbotron, I knew something was very wrong."

Dunham said that her boyfriend Jack Antonoff made it his screensaver because he found the height difference so amusing.

Apatow told Dunham she shouldn't compare herself to those ladies because it'd be like him comparing himself to Chris Hemsworth and Brad Pitt. "They are aliens," he said.

Dunham agreed and took it one step further. "I just think about it like this: There are certain people where I feel like it's like a lion and a tiger, or like a horse and a mule, or whatever, like a donkey and a horse, like, if we had sex, our kids would be sterile," said Dunham. "It's not like I even want to touch--like, I wouldn't even want to have sex with Chris Hemsworth; it would be so confusing and feel like f--king a dog--like the wrong thing to do. Really."

"I shan't be walking that runway again," said Dunham.
