Rob Kardashian pens a heartfelt tribute to Khloe in celebration of her 39th birthday

Rob Kardashian returned to Instagram on Tuesday to write a heartfelt tribute to his older sister Khloe in honor of her 39th birthday.

The TV personality, 36, uploaded two photos of the Good American founder and a lengthy caption, while other loved ones, such as mom Kris Jenner, also took the time to give the star a birthday note.

The first photo was a close-up selfie of the father of a child with Khloe as they sat next to each other. They gave small smiles to the camera for the quick shot.

The other image in the Instagram carousel showed the star posing for a sweet photo with Rob’s daughter Dream, six, who he shares with ex Blac Chyna.

“Happy birthday @khloekardashian,” he typed, followed by a slew of red balloon emojis. “I wish you nothing but good health and happiness forever my dear buttercup!”

Rob continued, “I love you so much and am so grateful to have you in my life and for all you do for Dream and me. I don’t know what I’d do without you.’ He added an assortment of emojis and another “happy birthday” to his sister.

Khloe jumped to the comments section to return the love, typing, “My baby!!!! My favorite person in the world. You are my heartbeat.’

The media personality was last active on Instagram earlier this year on Feb. 22 to pay tribute to his late father, Robert Kardashian, on what would have been his 79th birthday.

Notably, the lawyer died in 2003 after a battle with esophageal cancer. During his wedding to Kris Jenner, the couple welcomed Khloe, Rob, Kim, 42, and also Kourtney, 44.

Both Khloe and Rob appear to be very close, with the businesswoman also writing a loving tribute to her brother for his birthday earlier this year in March.

‘It’s one of my favorite days because it’s one of my favorite people’s birthdays!! My little bobby boy,” she had written at the time, along with a slew of photos of the two taken over the years.

“My wish for you is a thousand wishes and that they all come true. That you wake up one day and know with everything in your being that you are enough. You have always been enough,” she wrote, adding that her “wish” for Rob is “to be happy.”

“My wish is that you keep doing things that push you outside your comfort zone. Let this season be what it should be. Let it shape you how it’s meant to be,” and concluded the post by telling her younger brother how “proud” she was to be his sister.

In the past, Khloe has also opened up about her bond with Rob, and she’s gushed about that before People“Rob really is my best friend.

“I love, love, love him. He is always nearby. People think we don’t see him, but just because the public doesn’t see him doesn’t mean we don’t see him,” she further explained.

Of all the Kardashian/Jenner siblings, Rob notably leads a more private life as he focuses on co-parenting his six-year-old daughter with Blac Chyna, who also shares a son, King, with rapper Tyga.

While talking to Page six in March she opened up about co-parenting the two, saying, “With Robert and [Tyga]it’s never been like no bad blood or anything negative.

“But as we move forward into 2023, it’s all positive vibes with co-parenting,” she said, adding, “Everything is calm, there won’t be any more situations.”

Khloe received other loving messages from her family on Tuesday in honor of the big day.

Her “momager” Kris Jenner led the stream of testimonials with a gushing message that Khloe praised as the “life of every party!!!”

The message was accompanied by a heartwarming montage of Khloe as a child — including as a newborn in her mother’s arms. Kris also marked the occasion with a clip reel of Khloe’s childhood, including footage from various birthdays over the years.

Set to Stevie Wonder’s You Are The Sunshine Of My Life, the video often showed little Khloe happily running around with her older sisters. Congratulations on my beautiful bunny @khloekardashian!!!! Khloé, you are the sunshine of my life…” Kris began.

“You are the most amazing daughter, mom, sister, aunt, best friend, neighbor and such a big part of my heart!!!!!”

Kris wrapped up the lengthy caption, “I thank God every day for blessing me to be chosen to be your mama. I love you more than you will ever know and I cherish and treasure every moment we spend together. Mama xo.’

Kourtney, who is currently expecting her fourth child in total and first by her new husband Travis Barker, posted a storm in Khloe’s honor that morning.

She treated her 223 million followers to a series of throwbacks, like one of her and Khloe taking a stab at country chic by donning flannel and getting on trucks.

Kim enlisted TikTok teen singing duo Jake & Selby to record a custom video of them performing Patti LaBelle’s hit If Only You Knew for the birthday girl.

Khloe’s little half-sister, lip kit mogul Kylie Jenner, used her Kylie Cosmetics Instagram page to post a glamorous birthday album. Model photos of the couple were interspersed with charming throwbacks, like a couple in New York on their way to last year’s Met Gala.

In her caption, Kylie was livid at the birthday girl, writing, “happy birthday to the love of my life!!!!!” The makeup mogul added, ‘I couldn’t do it without you @khloekardashian you mean the whole world to me. i love you forever and beyond.’

“You took the words right out of my mouth,” Kourtney wrote in Kylie’s comments, while Kendall expressed his affection for “these pictures.”
