Kim Kardashian showed off her STUNNING physique on 'favorite island' in nude bikini and matching cowboy hat

Kim Kardashian, 40, may have spent the week supporting estranged husband Kanye West, 44, at his uber-exclusive album listening party in Atlanta, but it seems the week's been a bit much for the 40-year-old reality star because it seems like she packed up her bags and went on vacation back to her "favourite island".

On Sunday, Kim Kardashian went back to posting sultry snaps for her loyal 238million followers on Instagram, having taken a little break for a couple of days. The mom-of-four wowed in a nude bikini and matching cowboy hat, while she waded through the most gorgeous turquoise crystal clear water.

She captioned the idyllic post, "Back to my favorite island," although didn't reveal where that is, though that didn't stop fans from throwing out guesses like; "Turks and Caicos", the "Exumas" in the Bahamas, "Dominican Republic," and "Hawaii".

At the moment it isn't exactly clear if Kim is now on vacation or if the snaps were simply throwbacks from her previous visit, but either way, the SKIMS founder sure turned up the heat on a fairly boring Sunday afternoon. Check out her candid-like pics below.

Kim is a fan of a bikini selfie so often poses in a cute two-piece when given the opportunity, sometimes even racking in family members for bikini-clad pics for social media.
