Hélène Campbell dances with Ellen DeGeneres

Ottawa’s Hélène Campbell and Ellen DeGeneres shared their long-awaited on-screen dance on Tuesday.

The double-lung transplant recipient was finally able to take up the talk show host and comedian’s offer to visit her Los Angeles set, just about a year after she first spoke to DeGeneres on the show.

The Barrhaven native, 21, danced her way onto the set, got a big hug from the host and talked about the effect that Ellen has had on her life.

"I can’t believe I’m here," Campbell said on Tuesday’s episode. "The first time I talked to you . . . I had to get my oxygen turned up because you took my breath away."

Auctioning Bieber's underwear

Campbell received her new lungs in April and had been invited to come for the season-opening show in the fall, but she was still unable to travel.

She shot to fame early last year for her successful campaign to get Justin Bieber to tweet in support of organ donation awareness, around the same time she moved to Toronto to await a transplant.

Her original plan was to get DeGeneres to do the same, but the show’s producers one-upped that goal by surprising her on air over Skype.

On Tuesday, DeGeneres said Justin Bieber had signed a pair of underwear that she’d be auctioning off to help support organ donation.

Two blog posts with organ donation information were also posted to the show’s website, including one on Campbell’s "Give 2 Live" campaign for the Toronto General Hospital.

Prime Minister Stephen Harper took note on his Twitter feed, posting the message: "Great to see @alungstory recovering and enjoying her time on @TheEllenShow. She is an inspiration."
