Nicole Richie boob job implants gym tights black bottle juice bag red jacket leather studs sunglasses sneakers

Nicole Richie kept up her usual exercise routine, hitting up her gym in Ventura, Calif., Wednesday morning ... but there was one thing different this time.

The House of Harlow designer kept multiple parts of her body hidden! Nic kept a harsh burn on her face masked by shades. It looks like it could easily be from spending time at the beach or a chemical peel, because there's definitely a sunglasses tan there!

Nicole also kept her entire upper half covered-up in a crew neck top and an awesome studded leather jacket. This comes just one day after sources revealed that the Fashion Star mentor got a boob job over the summer to enhance her breasts post-babies.

Whether she got work done or not, we think Ms. Richie is looking great these days!
