We wonder how much she got paid to do this!

Kim Kardashian is the queen of paid endorsements, and this time the reality star is promoting diet shakes by flaunting her hot bod and wearing nothing but a white crop top and matching thong.

"#ad Little update for you guys. I’m on Day 9 of my Shake It Baby program from @flattummyco and I’m actually feeling so good. We had a massive Christmas this year and between my Mom's party, Christmas and New Years… I felt like it was impossible to fit in my regular work outs and eat healthy," she captioned the snapshot.

"But this program is giving me a kick in the right direction that I need. These meal replacement shakes are so good and it’s helping me get my tummy back to flat in the new year. The results I’m seeing and feeling are amazing and I’m so excited for the next few weeks. Because they’re all about getting women back on track… they’ve got a 20% off sale going on right now if you want to start 2018 off right… trust me, you’re going to want to check them out," she added.

We have a feeling her pay day goes up the more skin she shows. Can't knock the hustle.
