Lady Gaga postpones tour, blames it on 'The Little Mermaid' Ursula

London: Pop Star Lady Gaga has postponed two shows after being struck down with bronchitis. The 28-year-old singer was forced to pull out of a gig in Seattle on May 28 night and has cancelled another show in Vancouver on the American leg of her 'artRAVE Tour' due to the illness, reported Daily Mirror.

She took to Twitter to apologise to fans for the inconvenience and insisted she would reschedule the cancelled shows.

"I'm devastated I'm unable to perform this week. Ursula took my mermaid voice. I've come down with horrible Bronchitis. My deepest apologies to Seattle and Vancouver, we'll reschedule those shows and be back to make it up to you", Gaga tweeted.

The star is set to head to the UK in October and has added a number of extra arena shows in Birmingham, Sheffield, Newcastle and Glasgow.
