Lady Gaga will be performing tonight in Dublin's premier venue the O2 Arena as part of the Irish leg of the pop star's world tour Monster Ball. The pop starlet will be performing three sell out shows this week in Dublin as her entourage jet into town.

Gaga was spotted in London last night when the singer ordered fish and chips from Sea Shell Fish Bar in Maida Vale. There wasn't enough space to park her tour bus so her security staff delivered her food straight to the bus before they started their journey to Wales where they intended to board a ferry destined for Ireland.

Speaking about her tour she told KIIS-FM’s Ryan ­Seacrest about the theme for the show: “It has a New York theme, it's a story, and the story is that me and my friends are in New York and we're going to the Monster Ball, and we get lost.

"It's still called Monster Ball, but it's more of a musical and less of a concert,” she added.

The 24-year-old recently celebrated one billion views on YouTube and tweeted to fans about the success: "We reached 1 Billion views on YouTube little monsters! If we stick together we can do anything. I dub u kings and queens of YouTube! Unite!"
