Rob Kardashian is keeping up with a special occasion.
Indeed, the Kardashians star celebrated his sister Khloe Kardashian’s 41st birthday with a sweet photo on social media.
“Happy Birthday my baby!!!!!” Rob wrote on his June 27 Instagram Stories, which featured a throwback of him and Khloe twinning in denim outfits as kids. He fittingly included a few dancing and teary-eyed emojis before adding, “Yayyyyyyy, I love you so much!!!!”
His tribute didn’t stop there, as the 38-year-old—who shares daughter Dream, 8, with ex Blac Chyna—also posted a photo of Khloe bonding with their late dad, Robert Kardashian Sr.
“Dad would be so proud of the woman and mother you have become,” he continued. “I am so proud of who you have become! You have the biggest heart of anyone I know and I love you!!”
