There's nothing like blowing off steam after your estranged husband airs out your dirty laundry to the world.Kim Kardashian showed off her morning workout routine on Friday, February 18, after a stressful week dealing with Kanye West's public pleas for reconciliation and attacks on her beau, Pete Davidson, with whom she's been linked to since October 2021.Sharing a boomerang video to her Instagram Story of her on a stair master, the reality wrote: "Morning Workout 6am."Hours after sweating out the stress Ye most likely inflicted on her life, given that he publicly slammed her parenting style, shared private messages between the former flames, as well as between Davidson and West, and then bashed the comedian for making fun of his mental health, Kardashian enjoyed some time with her kiddos.KANYE WEST PLEADS FOR GOD TO 'BRING OUR FAMILY BACK TOGETHER' AS KIM KARDASHIAN BOASTS SHE 'FEELS REALLY GOOD' WITH CHANGES SHE'S MADE IN HER LIFETaking to her Instagram page, the KKW beauty founder shared an adorable snap of her youngest children showing each other some love. In the photo, Chicago, 4, kissed her little brother, Psalm, 2, on the forehead while wrapping her arm around him. "Chi & Psalm," the mother-of-four — who also shares North, 8, and Saint, 6, with West — captioned the post.Earlier this week, Kardashian spent some one-on-one time with her eldest, as the two enjoyed dinner together on Wednesday, February 16, at the swanky Japanese restaurant Nobu Malibu, per Daily Mail. The mother-daughter duo's outing came days after North joined her dad at the Super Bowl in L.A.KIM KARDASHIAN TO TESTIFY ABOUT BLAC CHYNA'S 'HISTORY OF SUBSTANCE ABUSE,' KYLIE JENNER TO RECOUNT ALLEGED THREATS IN ROB KARDASHIAN'S SUIT AGAINST HIS EXKardashian filed for divorce from West last February and filed to be declared legally single in December. It's clear Kardashian and West have their differences, but things between the two went from bad to worse as of late after the "All Of The Lights" hitmaker trolled the Big Time Adolescence star earlier this week on his Instagram page and declared "Kimye forever."And while it seemed everything began to eventually cool down — as West removed his scathing posts and acknowledged "sharing screen shots was jarring and came off as harassing Kim" — he appeared to backtrack when he called the Saturday Night Live star out for a previous skit he did about the rapper's mental health. “HI SKETE YOU GOT ANYMORE MENTAL HEALTH JOKES FOR ME?” he wrote alongside a screenshot from the skit, using his derogatory nickname for Davidson.The father-of-four — who called it quits with ex Julia Fox amid his social media outburst — has since deleted the post, but the SKIMS founder already unfollowed the father of her children. Meanwhile, West followed Davidson on Instagram after he recently joined the social media platform amid all the drama. As for who Davidson is following: His new girlfriend and Sebastian Stan.
