The 35-year-old was last seen on August 18 in West Hollywood, California and was reported missing that day, according to LAPD officials.
His friends have said they are very worried about him.
"This is very unusual for him to be missing. He hasn't done anything, not shown up for no reason, no note or anything," friend Mel Espinoza told ABC7 News.
In 2013, Strebel spoke to INSIDE EDITION about his surgeries to look like the “Baby Baby” singer.
He said: “I looked at [Bieber’s] pictures and I was like, 'Wow, that's exactly what I'm supposed to look like!'"
When asked why he would go under the knife to look just like Justin Bieber, he answered: “I just want to have the youthful features of him and just look as young as he does.”
Anyone with information on his whereabouts was urged to contact the Los Angeles Police Department.
