Kristin Cavallari is pregnant with her third child (and first girl!), so naturally the lady deserves a little R&R—and she's indulging! The Laguna Beach alum hopped on Instagram on Sunday, Aug. 16, to share a casually luxe photo of herself cradling her blossoming baby bump while lounging at the spa.

"Thank you @virginhotelschi [Virgin Hotels Chicago] for the amazing prenatal massage," Cavallari, who married Chicago Bears quarterback Jay Cutler in 2013, captioned the pic, adding a halo-topped angel emoji and the hashtag #spoiledatthespa. She modeled a tight black dress, fedora hat, and flat sandals for the relaxing day.

It's hardly Cavallari's first impressive maternity ensemble. The Fabulist host, 28, has rocked lace minis, fitted maxis, and even short shorts, and she's made sure to share every outfit via Instagram.

Of course, the mom to Camden, 2, and Jaxon, 15 months, hasn't just been looking cute—she's been working hard, too. Gearing up to release her first book, Balancing in Heels (due out March 2016), Cavallari shared two potential covers for the how-to guide, asking her fans to choose a favorite. Speaking directly to her loyal fans, Cavallari captioned both options, "I want you guys to pick which book cover you like better!"
