A rally cry from Justin Bieber asking fans to become organ donors has done wonders for Ontario's Trillium Gift of Life Network, which has seen a boost in registrations from people offering to become organ donors since the plea was made last week.

Bieber, who frequently makes hearts throb, turned his attention toward other organs when he responded to an Ottawa woman's request for help.

Helena Campbell, 20, has been diagnosed with idiopathic pulmonary fibrosis – a rare lung disorder that requires a transplant. She has moved to Toronto for treatment and is on a waiting list for new organs.

Campbell has kept an account of her experiences on www.alungstory.com and has been trying to rally support for organ donations across the province.

Last week, Campbell and her friends came up with a plan to draw Bieber into the campaign by contacting him en masse through Twitter.

"Hey @justinbieber! I BELIEB you should use that Canadian voice of yours and help save lives like mine #beanorgandonor beadonor.ca #giveblood," Helene wrote from her Twitter account @alungstory.

The star from Stratford, Ont., forwarded her message to his 16.5 million Twitter followers, and followed it up with a plea of his own, asking followers to help spread the word.

Trillium Gift of Life Network, which operates the beadonor.ca website, saw an immediate spike in traffic to the website and an explosion in online registration.

The health network has received some 1,500 online registrations since Campbell began her campaign last Thursday. That is more than four times the amount the network usually receives.

The Trillium Gift of Life Network says there are about 1,500 people in Ontario awaiting a life-saving organ donation, plus more waiting for tissue transplants.
