Pop star Ke$Ha has taken aim at celebrity blogger Perez Hilton for publishing leaked photographs showing her in intimate poses with her ex-boyfriend, accusing him of "single-handedly" ruining the relationship.

Images of the Tik Tok hitmaker and her then-partner, named only as Harold, emerged online in 2010, and the singer is convinced their publication is the reason the romance came to an end.

Speaking on her new MTV show, Ke$ha: My Crazy Beautiful Life, she says, "(Hilton) single-handedly ruined the only relationship that's ever meant anything to me."

Ke$ha is seen fighting back tears as she declares, "He stands for everything I hate. Everything I'm against."

The star opened up about the doomed romance in her track The Harold Song, which featured on her 2010 album Cannibal.
