Katy Perry brought her California Dreams Tour to Dublin this week on the heels of an escalating feud, which unraveled on the Internet with tour collaborator Calvin Harris.

California girl Katy and the Scottish DJ had previously joined forces for the Australian and British legs of her world tour, only to have Harris pull out before the Irish gigs took place.

Reports surfaced that Harris was unhappy with the production quality on the tour, leading Perry to publicly confront Harris’ sudden withdrawal on the social networking site Twitter. After a series of back and forth tweets, Perry blasted “it’s fine, I’m used to you canceling on me, it’s become ur (sic) staple!”

Despite the setback, Perry, who married British comedian Russell Brand in October in a lavish ceremony in India, let loose in Dublin tweeting after her sold out gig in the O2 arena “DUBLIN you were GORGEOUS tonight! I ♥ YOU!”
