Kim Kardashian and Kanye West Solve the Mystery of their Mansion’s Spray Painter

This Is What Kanye West Should Name His Album
... According to Kim Kardashian's Twitter poll.

Call them crime geniuses.

Kim Kardashian and Kanye West’s new mansion was spray painted by a mystery pranker, which put security officials and neighbors on high alert. The couple was le chill about the whole situation because they knew exactly who did it.

TMZ reports…

We found out the Wests graffiti’d their own place!

Our Kardashian sources tell us the family got a bunch of calls Wednesday morning when people living next to the compound noticed the his and hers “I heart” paint job. We’re told Kim calmed everyone down, because she and Kanye had gone to the house — which is still under construction — and did the tagging on Tuesday.

We know what you’re thinking. Yes, they love themselves, but not that much. The house is getting replastered Thursday, so they decided to have some fun.
