Bella Hadid suffered a nip slip while on the runway for the Alexandre Vauthier show in Paris yesterday, but she is such a pro, she played it off and didn't even flinch! Either that, or she didn't know that her lady bits were peeking through her bustier!

Gigi's little sis is really trying to make a statement off the catwalk, too, during her time in the City of Lights. After work was done, she changed into 90s jeans, skinny glasses, and dad sneakers for the after party. In our opinion, celebs are taking this whole trend TOO far. What happened to wanting to look attractive?!

In other Bella news, rumor has it the brunette beauty has been getting cozy with Kendall Jenner's ex Jordan Clarkson. She and Kenny are friends, so we'd think this would be a no-no in girl code, but apparently it wasn't a problem.

We still want her to get back with The Weeknd!
