AceShowbiz - Kim Kardashian knows the perfect gift for her fourth wedding anniversary with husband Kanye West. No stranger to showing off some skin, the "Keeping Up with the Kardashians" star is reportedly planning to give her rapper husband a book of nude selfies.

"Kim has decided she wants to spice up their sex life," a source close to the family tells Heat magazine. "It'll be totally classy and in the style of her selfies book." For those who need a refresher, Kim released a 352-page selfie book, "Selfish", back in 2015. It included a number of her best selfies as well as a slew of nude pictures of herself.

According to the source, Kim is determined to keep her husband happy after witnessing what sister Khloe Kardashian is going through right now. "After everything Khloe's going through with boyfriend Tristan [Tristan Thompson], Kim's decided to take pre-emptive action," the insider goes on saying. "She's going to get a selection of her nude selfies, which is so Kim."

The report arrives after Kim and Tristan unfollowed each other on Instagram. It's unclear what caused them to unfollow each other, but it's speculated that the reason behind their act is due to Kim's recent appearance on "The Ellen DeGeneres Show", on which she talked about the cheating drama.

"I just don't know how to describe it, besides it's just so f***ed up!" she said in the episode that aired on Monday, April 30. "We really were rooting for Khloe... and she's really doing the best that she can; it's a really sad situation all over."

She then noted that she would not bad mouth any of her siblings' exes, especially if there's a kid involved. "I'm gonna, like, keep it classy and not talk too bad," she told Ellen DeGeneres. "One day True is going to see this and, you know, it's so messed up."
