Arriving in her gym clothes with her shades firmly in place, Kim was joined by two friends as she relaxed inside the salon.
Stepping out without make-up on, the pregnant star enjoyed an afternoon gym session before hitting her favourite nail salon in Beverly Hills.
The 32-year-old is staying in top shape ahead of her due date this June, making sure she's following personal trainer Tracy Anderson's strict pregnancy workout plan.
And it certainly seems to be paying off, with Kim looking every inch the yummy mummy - despite leaving her lashings of lippy and contouring make-up at home.

Tracy, who is responsible for Gwyneth Platrow's stupidly-hot body, reckons Kim will have no trouble slimming back down following the birth this summer.
She said: "I know she will [get her body back]. She's so young, and she's got me helping her, so she's going to look better after pregnancy than she's ever looked. I guarantee it.
"It's so important that once the doctor releases you to start working out again."
But poor Kim was cleary feeling a little low yesterday, apparently receiving some nasty jibes on Twitter.
Ever the professional, she snapped back on her website, uploading a snap that read: "If people are trying to bring you down, it only means that you are above them."
