Justin Bieber was seen attending his "Believe" movie premiere at the Regal Cinemas in Los Angeles, California (LA) on Wednesday, Dec. 18, 2013, just days after saying in an interview that he was retiring from the music industry. Bieber's supporters including fans and celebrity friends such as actor Jaden Smith (Will Smith and Jada Pinkett-Smith's son), mentor Usher and Kylie Kardashian of "Keeping Up with the Kardashians" fame, came in full force.

Of course, Bieber's "momager" (mom + manager) Pattie Mallette also showed her support for her beloved son and even posed with him on the violet carpet. Even Justin's grandmother Diane Dale attended and wore a red dress that matched her grandson's red suit. How festive and perfect for the holidays, right?

Justin wore an untucked white shirt under his red suit and accessorized it with a gold chain. Even though the premiere was held at night, Bieber wore dark shades like other famous celebrities. His outfit was actually reminiscent of Coca Cola's colors or Santa Claus. At least, he suited up for this special night. Bieber is usually seen in his shows wearing a white tank or wearing nothing on his upper half body at all.

Graffiti artist Alec Monopoly was also there because he created an installation for the said event using the cover art of Bieber's singles from "Music Journals" as inspiration. Monopoly painted his art work live on-site. After completing it, he auctioned it off for charity.

Bieber also sprayed some graffiti on a wall there. It seems like this is Bieber's new found hobby. Will he retire from his very successful music career to become a graffiti artist instead?

Speaking of Bieber's alleged plans of retirement, watch the video below of Bieber addressing it in an interview with MTV News correspondent Christina Garibaldi.

Garibaldi also caught up with "Believe" director Jon M. Chu and producer Scooter Braun as well as Sean Combs and Bieber's mentor Usher Raymond.

Now that Justin Bieber was seen at the "Believe" movie premiere in LA after saying that he was retiring and addressing the retirement rumours, Belieber fans can heave a small sigh of relief because it looks like Bieber retiring from his successful musical career will be something that will happen way into the future. However, Bieber is still very cryptic and evasive about the supposed retirement in the MTV interview. Justin probably just needs a bit of break from his hectic schedule especially after touring worldwide for his "Believe" tour that's why he made that comment. Justin Bieber's "Believe" movie will be out on Christmas Day, Dec. 25, 2013 (Wednesday). Click HERE for other videos about it.
