Christina Milian, 37, shows off abs in a makeup-free bikini photo

Christina Milian isn't letting cooler Midwestern temperatures get in the way of a good tanning opportunity.  

The singer, 37, shared a few makeup-free photos Wednesday showing off her killer abs in a snakeskin bikini.

Milian tagged Chicago as her location, which means she might have been a little chilly— the Windy City isn't supposed to get warmer than 55 degrees this week. But that didn't stop Milian from showing off her summer bod a few months early. 

"Tanning in the city ain’t easy but I’ll make happen," she captioned the Instagram post. 

Milian has one daughter, 9-year-old Violet, with ex-husband singer/producer The-Dream.
