Kanye West turned 39 on Wednesday and, "since it's Kanye's birthday week," as Kim Kardashian West writes on her website, she researched their astrological compatibility -- including their sex rating based on their star signs.
"I did a little research about Libras and Geminis and found out they're a perfect match!" Kim said. "One website even said that we were one of the best matches in the zodiac. We're both air signs on the same wavelength. SO true! We've had an amazing connection right from the start."
The 35-year-old reality star revealed that sisters Khloé Kardashian and Kendall Jenner first got her into astrology and explained that her and Kanye's zodiac signs dictate they both love "travel, surprises and communication."
As for their sexual compatibility, Kim brags, "Libra/Gemini sex gets a 5-star rating because we're so in tune with each other."
Earlier this week, the Keeping Up With the Kardashians star shared a sweet shot with her rapper hubby on Instagram and wrote, "Happy birthday to my best friend! I usually would be scared for us getting 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," Kim concluded.
