Copycat vandals have struck the California boutique owned by reality TV star Kim Kardashian and her sisters Khloe and Kourtney - just a day after their new Florida store was sprayed with graffiti.

The Keeping Up with the Kardashians stars were outraged when their South Florida fashion store Dash was defaced in a graffiti attack on Wednesday, just a day before its grand opening.

And now vandals have struck their Dash boutique in Calabasas, California - marking the shop with the same “GUK” graffiti that appeared on the Miami storefront, in addition to a tag that reads: “We love you Kim!”

Khloe writes on her Twitter.com blog, “Wow! I knew there were haters but this is crazy! Now our LA DASH was vandalized! Graffiti again Pathetic! You still can’t stop us though!!! …People are a**holes.”

Police are investigating the incidents, reports TMZ.com.
