Some people may question whether Ugg boots are "cool," but when you have the likes of Jennifer Lopez and Rihanna wearing them, it's hard to doubt the fact that the brand is in people's

good graces again. I certainly wore them with abandon in the early 2000s, but what's old is new again, after all. 

I put together a preview of how celebrities are wearing Ugg boots nowadays, and the outfits include everything from leggings and sweatpants to baggy jeans and shorts. So without further ado, scroll down to see how J.Lo, Rihanna, Hailey Bieber, Selena Gomez, Irina Shayk, and Katie Holmes are all wearing Uggs, and shop the brand for yourself. Plus, I also included similar brands since Ugg styles tend to sell out quickly.
