Justin Bieber and Selena Gomez enjoyed a romantic helicopter ride in between rehearsals, before they took the stage in Toronto for Sunday night's MuchMusic Video Awards.
Bieber, 18, rented a chopper Saturday to take Gomez over the falls and to Stratford, Ontario, which is home to North America's largest classical repertory theater.
"They were very excited," the source added.
Bieber fetched Gomez at the Toronto airport Friday when she flew in from Los Angeles.
The couple were kissing and hugging as they departed via private car.
