By Iona Kirby and Rachel Levy

She welcomed her second child in May.

And on Thursday, Kristin Cavallari was finally snapped with her son Jaxon Wyatt, as she stepped out in her residential city of Chicago.

Yet, it was hard to believe it's only been a little over a month since the 27-year-old reality star gave birth.

The Hills alum displayed her impressive form in a tiny pair of olive green distressed denim shorts and a loose off-white blouse.

Kristin was last seen running errands in Los Angeles on April 9 but posted a selfie on Instagram of her outfit just 15 hours before revealing she had given birth.

The blonde admitted in March that she and Jay opted out of vaccinating Camden and were not planning on vaccinating their second child either.

'We didn't vaccinate. I read too many books about autism and the studies,' Kristin said in an interview with FOX Business' The Independents.

'There’s a pediatric group called Homestead, or Home First ...They've never vaccinated any of their children and they haven’t had one case of autism. And now one in 88 boys is autistic, which is a really scary statistic.'

Amazing. Jessica Simpson was pregnant for what seemed like forever. Kristin's pregnancy lasted about 10 minutes. And she looks amazing.
