The laughter we've shared and share I'll crave forever. There's something about you and I... We are two peas in a pod. We go together like peanut butter and jelly. We are twin souls. Kourt you are irreplaceable to me. It's hard to put into words the way I feel about you and our bond."

"Nothing can break you and I. My wish is that you continue to sparkle and radiate love and happiness. I pray that the magic in you only gets stronger and the fire of life I see in you never ever dims," Khloé concluded her message to Kourtney. "Together forever and even afterwards 🤍 Suzanne"

As for Kourtney herself, the reality star shared a post to her Instagram page highlighting the series of cakes that have been shared on her birthday trip with friends and family. 

Kourtney captioned the post "mood 🎈," with the first photo showing her laughing on a yacht alongside a large cake with a glittery cake topper that reads 'Happy Birthday To The Most Exciting To Look At.' The topper refers to the viral insult lobbed at Kourtney by Kim, who previously called her older sister "the least exciting to look at" during an episode of their former reality show, Keeping Up with the Kardashians

The other cakes read "Aries Baby" and "Just Living Life," a saying Kourtney often uses on the family's Hulu show. 

It's a fitting celebration for Kourtney whose had an exciting several months: the reality star welcomed her and Travis' bundle of joy on Nov. 1. The baby boy joins Travis' children -- son Landon, 20, and daughter Alabama, 18, whom he shares with ex-wife Shanna Moakler, and stepdaughter Atiana De La Hoya -- as well as Kourtney's three kids, whom she shares with ex-Scott Disick -- sons Mason, 14, and Reign, 9, and daughter Penelope, 11.

A source told ET back in January that Kourt "is beyond elated since welcoming Rocky."

"Spending time as a big family with their new addition has been amazing for Kourtney and Travis," the source said of the pair's blended family. "Kourtney’s family is so excited for her, and they already love Rocky so much. They’ve been showering Rocky with love and soaking up this time together."

The source also said that Travis seamlessly transitioned into his role as a father once again, sharing, "Travis has always been a great dad, which is one of the reasons Kourtney was so drawn to him at the beginning of their relationship, and seeing him in this role again in a different way has been very special. They're doing great as a couple and continuing to be there for each other in this new chapter."
