前身为I Hate Kate, 被疯狂女歌迷骚扰，遂改名。Darling Thieves, formerly known as I Hate Kate is an alternative rock band from Huntington Beach, California. The band was founded in November, 2004 by former Zebrahead frontman Justin Mauriello, to explore his musical options.

Justin Mauriello started I Hate Kate in 2004, while still in Zebrahead, as a creative outlet. The band has seen a steady rise in success. I Hate Kate played with the likes of Social Distortion, Chevelle, Hot Hot Heat, The Bravery, The Living End, My Chemical Romance, Unwritten Law, Secondhand Serenade, and Shiny Toy Guns. Tours have taken them throughout the U.S., Canada, and Japan.
December 2007, the band took to the studio with platinum producer Mark Trombino (Jimmy Eat World, Blink-182, Sugarcult), recorded new songs and remixed previous tracks. They released their first full-length album "Embrace the Curse" on June 24, 2008 under Glassnote Records.
In early 2010, the band recorded a new album, Race To Red, with producer Lee Miles (Tickle Me Pink, The Red Jumpsuit Apparatus, Puddle of Mudd). The band released the first single off the album, "Free Without You", on January 12.

In June 2010, a woman named Kate, whom the band was named after, left lead man Justin Mauriello an angry voicemail about the use of her name for the band and threatening legal action. The band felt it was in their best interest to change their name to Darling Thieves.

As the Darling Thieves they have been headlining their own shows and sharing the stage with the likes of Hollywood Undead, Hyper Crush, and New Politics.
