More than 22,000 people packed into the event grounds in Charlottetown last night to see one of the world's biggest country music stars.

Shania Twain, who performs regularly in Las Vegas, left the big city to take part in the 2014 Celebrations on P.E.I.

From the moment she took the stage the energy was high.

A sea of fans captivated by a show many won’t soon forget.

Twain says she won't either.

“I mean I hope everybody was happy but they sounded so happy and everyone was really excited and I just think we were all in it together and had a great time,” she said.

This is the first time Twain has performed on the Island but says she visited as a teenager.

Hannah Reardon came from Nova Scotia to celebrate her 12th birthday.

"It's awesome being here on my birthday,” she said.

Twain also had a birthday this week and says she was happy to celebrate it on Canadian soil.

"Well I just feel at home here and I relate so much to the people and the culture,” she said.

Twain wrapped her visit to the Island with fireworks over the harbour.

Twain is the world’s best-selling female country artist of all time with more than 75 million albums sold.

She has multi-platinum album sales in 32 countries, has the eighth-biggest selling album of all time in the U.S. and 18 top 10 songs, eight of which reached #1.
