Is it a sin to take a glimpse at this nip-slip photo?

Sin City star Jessica Alba showed a little too much skin while out in NYC on May 6, as she was photographed suffering a nip slip, according to E! Online.

Jess appears to be in the process of shedding one of her outer layers in the photo, causing her to inadvertently expose her sheer bra.

In doing so, her right nipple had a coming-out party of sorts.

Later that evening, Jessica made sure to cover up at the 2013 Met Gala, which she attended with hubby Cash Warren.

The actress, who turned 32 last week, can be seen later this year in the films Machete Kills and the Sin City sequel. 

And while Jessica may have bared more than she wanted to this week, don't expect her to follow suit in a film.

"I can act sexy and wear sexy clothes, but I can't go naked," she has said about nixing nude scenes. "I come from a very Catholic family, so it wasn't seen as a good thing to flaunt yourself like that." 

In other words, get your fill of this photo, since it's all we'll be getting.
