Justin Bieber is spreading a message while also perfecting his skill with a paint can. The singer, who was spotted practicing his street art technique in Colombia, gave his musician pal (and fellow graffiti artist) Chris Brown a shout out on the wall. Inside of a pink arrow on the wall, Biebs spray-painted the words "Free Breezy" in red, referring to the 24-year-old singer checking into rehab for anger management on Tuesday, Oct. 29.
