After her show-stopping style at Haute Couture Week in Paris, Céline Dion took the trip across the channel to London.

The Canadian icon was on hand to kick off the British Summer Time Festival in Hyde Park.

Dion took to the stage in an 80s inspired blue jumpsuit where she performed such hits as “Think Twice”, “I Am Alive” and “Because You Loved Me”. Other outfit changes included an emerald green dress and a yellow “Beauty And The Beast” inspired ball gown.

Sam Smith was also at the performance where he and his friends sang along to all the songs.

“Celine Dion just changed my life,” Smith captioned a video on Instagram. “Just look at her,” you can hear him saying in the background.

More of Smith’s sing-along were featured on his InstaStories including “My Heart Will Go On”.

Dion closed out the concert with John Lennon’s “Imagine”, telling the crowd she wanted to end the night “with the message of peace and harmony in the best way I can.”

Her performance was announced back in January, at the time she said, “I’ve got a big craving for some bangers and mash and some sticky toffee pudding. So I’m heading over to London this summer, to headline the Barclaycard British Summer Time Hyde Park festival on July 5 and I can’t wait to see you guys.”
