Kim Kardashian says she’s getting her ‘mind and body right’ amid Kanye West divorce rumors

Kim Kardashian is trying to kick off the New Year on the right foot despite a divorce from Kanye West that reportedly looms ahead.

The KKW Beauty mogul, 40, shared a note to her fans on Tuesday -- via her Instagram Stories -- that she and her sisters are launching into an intense workout regimen for the next 30 days.

"Sister Boot Camp starts this month! Plant Based and Two workouts a day for 30 days to get our mind and body right for this year!" Kardashian captioned the Story, in which two pairs of sneakers are featured – one a pair of Yeezy’s, created by her husband and the second from a competing brand, which West used to design for in years past.

News that Kardashian is "preparing to divorce" the rapper and fashion designer, 43, came on the heels of an announcement from Kardashian that she had sold a 20% stake in her company to Coty for $200 million.

She is very grateful to have her sisters to lean on."
