Khloe Kardashian is wishing her younger brother good luck.
After all, Rob Kardashian turned 38 on March 17 (a.k.a, St. Patrick’s Day), and the Good American founder—alongside her kids True, 8, and Tatum, 2—gave him more than a four leaf clover to celebrate his special day.
“Not sure what the lime represents,” Khloe, 40, captioned the photo on her Instagram Stories, which sees her and ex Tristan Thompson’s two kids fittingly dressed in green to honor their uncle’s latest trip around the sun. “But it’s green.”
Tatum, who looks like a spitting image of Rob, sported an all-green sweatsuit while his older sister topped off her charm-inspired outfit with a few bracelets and, of course, a random lime.
Khloe and sister Kourtney Kardashian also showed off their brother’s birthday cake, which resembled a black jackpot slot machine that featured three icons: a football, baseball, and a basketball, on their Instagram Stories.
The Kardashians star also showed Rob—dad to 7-year-old daughter Dream with ex Blac Chyna—some love in a sweet tribute, where she complimented him as “one of the most loving, hysterical, gentle but insane, and downright majestic souls” she’s ever known.
“Bobby, I couldn’t be prouder or more honored to call you my brother,” Khloe began the post, which sees her and Rob posed with their late dad, Robert Kardashian Sr. “Walking through life with you by my side is one of my greatest blessings, and I don’t take a single moment of it for granted. The fact that I can call you whenever—about absolutely nothing—and you actually answer? That’s love!”
That’s not all, though. Kris Jenner also gushed over her youngest with a touching throwback photo carousel on Instagram, complimenting their bond as “one of her life’s most special blessings.”
“I thank God He chose me to be your Mom,” the 69-year-old continued. “You are such an incredible Dad, Son, Brother, Uncle, Grandson and best friend and I cherish every memory we have made.”
This isn’t the first time the Kardashian tribe and their children have honored Rob, who’s notably stepped away from the spotlight since his 2016 reality show, Rob & Chyna. Last March, Khloe shared an adorable video of her kids singing “Happy Birthday” to the sock designer on Instagram.
