The incident at the showbiz power couple's abode is said to have shocked neighbours and security guards until they discovered that the unknown graffiti artists were Kim and Kanye.

Sources told gossip website TMZ that the pair were alerted to the news on Wednesday morning (03.02.16) after pals spotted "I heart Kim" and "I heart Kanye" spray painted onto the outside of their plush property, which is under construction.

But Kim, 35, later reassured concerned neighbours that she and her husband - who have daughter North, two, and eight-week-old son Saint - had in fact done the deed.

The couple are said to have tagged their house because it is being re-plastered later today (04.02.16).

This comes after it was reported Kanye, 38, fired the contractor who is working on the pair's new Hidden Hills marital home in California following a visit last month.

A source said at the time: "He went around complaining how so many things that were supposed to be done were not.

"He fired the contractor and everyone on the property at the time!

"He's really frustrated that it's taking this long."

Kim and Kanye purchased their new pad in March 2015 but moved in with her mother Kris Jenner in August so renovation work could be carried out on their plush property.
