Part of the extended celebrations means that some of the sisters get their own individual covers. Kim and Kourtney shared pics of their solo covers earlier Wednesday afternoon on Instagram.
The sisters are pictured wearing similar tight, white shirts, though Kim's 15-carat wedding ring is featured prominently in her solo shot.
Kourtney made headlines Tuesday afternoon for posing nude in "Vanity Fair."
The reality star and mother of three tweeted out the racy photo, thanking photographer Brian Bowen Smith for including her in his "Metallic Life" series.
