Kim Kardashian shared a sweet message for Kanye West's 39th birthday on Wednesday.
The 35-year-old "Keeping Up with the Kardashians" star posted the note and a collage of photos on her website.
Kardashian and West married in Florence, Italy, in 2014, and share 2-year-old daughter North and 6-month-old son Saint.
"Happy birthday to my best friend! I usually would be scared for us to get older, but as each year passes, I'm just happy we have more time on this Earth together! I love you so much and hope this year brings you so much happiness," the star wrote.
Kardashian's mom, Kris Jenner, and half-sister Kendall Jenner were among the other Kardashian-Jenners to wish West a happy birthday.
Kris accompanied her post with a rare picture of the rapper smiling.
"Happy birthday to my son, North and Saint's daddy and Kim's soul mate, #KanyeWest," she said on Instagram. "To say you are special is an understatement... you are one of a kind!!!! You inspire, you lead, you're the most incredible father and a wonderful friend. I'm so proud of you and I love you so much."
"Happy birthday, Kanye! You're such a creative and innovative person," Kendall wrote on her website. "You constantly inspire me to just be me because you are always so true to yourself. You and Kim are ultimate couple goals! You're the best husband my sister could have. We love you!"
Kardashian and her family star on E! series "Keeping Up with the Kardashians," which airs Sundays at 9 p.m. ET. Actress Helen Mirren praised the star in an interview this week for helping to redefine beauty standards.
