Stamos, who has been a forever fan of the "King of Rock 'n Roll," joined young patients from Le Bonheur Children's Hospital at the lighting ceremony at Presley's former home, along with hundreds of other onlookers.
The Full House actor told the Associated Press following the ceremony that the sideburns were intentional.
"It's so funny. I had a beard, and I was like, 'I better shave this and I'll keep the burns in tribute,'" Stamos said.
Stamos owned up that the pompadour he also sported was not really his hair.
"This is a new wig. I put a special wig on for tonight," he said.

Stamos is often associated with Elvis Presley. His voice is featured on the iPad tour of the home and Full House fans will remember well when the actor dressed up as the "King" for an episode of the hit TV show. He also visited the mansion-turned-museum for a 1990s television special, where he was able to play one chord on Presley's piano.
"I think the first time I saw him, the word 'supernova' came into my head," Stamos said of his idol. "I was just immediately in awe. He had it all. Nobody's had it all. People have good voices, or they're good looking, or their charismatic, or they're good people, but it's the combination."

Stamos told the AP he is appearing in the upcoming ABC musical comedy series Galavant, which he describes as "a cross between The Princess Bride and Monty Python."
