An artist has claimed Courtney Love owes him thousands of dollars for designing merchandise for her tour. Greg Frederick, a long-time fan of the singer, has said he was promised a percentage of the money made from the sale of his T-shirts at her concerts. He said: "It's been devastating. "My biggest dream has turned into my biggest nightmare. It has sunk me very low." The New York-based artist explained he has yet to receive any money from the merchandise sales, despite his designs being sold on four of Courtney's tours, including one with Lana Del Rey. Frederick first started working with the singer when he contacted her on social media, saying his "wildest wish" would be to "work with Courtney Love and design her next concert tour T-shirt". And in an email written in June 2013, Courtney described his designs as "amazing", adding: "We could make up to 5k a night if it's done right."
