“I thank God every day for our relationship and the relationship that our children get to have,” she continued, referencing her and Tristian Thompson’s 1-year-old son, Tatum, and 5-year-old daughter True’s close relationship they have with Rob’s daughter, Dream, 7, whom he shares with ex Blac Chyna.

The Good American founder further said she has “so many hopes and dreams” for her brother, including him realizing he is “enough.”

“Be the greatest person you can possibly be,” she said. “Do things that make you proud. For you to have gratitude for even the smallest of things. Surround yourself with people who bring.”

Khloé urged him to continue being “loving” and “compassionate,” concluding, “Don’t try to be perfect, Simply try to Be better than you were yesterday.”

As for Kourtney Kardashian, 44, she took to her Instagram Story to share a more low-key message paired with old photos of Rob on his birthday, which also lands on St. Patrick’s Day.

“The best brother in the world,” the Lemme founder wrote alongside a throwback photo with her little brother and five heart emojis.

Kim Kardashian, 43, also posted a picture of her and Rob for their early years. Alongside her photo, she wrote, “Happy Birthday to the sweetest funniest best brother in the world! @robkardashianofficial I love you so much and so blessed to have u as my brother! ♾️🩶🍀.”

The SKIMS founder’s heartfelt post comes hours after she teased her adventure to find Kate Middleton amid ongoing concerns about the Princess of Wales’ well-being.

However, Kim’s witty joke didn’t sit well with several royal fans as they slammed her for “spreading rumors” about Middleton after she had abdominal surgery.

“Nothing like a Celebrity who allegedly hates rumors, spreading rumors,” one fan wrote. “It’s not like people from your fam have gone into hiding (rightfully so) during pregnancy or other medical reasons… this caption isn’t it.”
