IN SYNC: Kanye West and Kim Kardashian in.
Hollywood stars expect only the best.

And for Kim Kardashian, that includes bedroom shenanigans.

The reality TV star says sex with hubby Kanye West literally “gets a five-star rating”.

But the rating is not based on past experiences, no, Kim sought the answers to her bedroom blues in the heavens.

The Keeping Up With the Kardashians star was researching the “astrological compatibility” of herself and the rapper in honour of his 39th birthday last week, and was very pleased with the results.

She revealed on her website: “I did a little research about Libras and Geminis and found out they’re a perfect match!

“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...

“Libra/Gemini sex gets a 5-star rating because we’re so in tune with each other.”

The 35-year-old beauty - who has children North, two, and Saint, six months, with Kanye - further wrote: “My serene presence soothes a Gemini, and Kanye inspires me during his creative surges.”

Apparently, her sisters Khloé Kardashian and Kendall Jenner introduced Kim to the wonders of astrology.
