Justin Bieber is telling people how supportive he is of Chris Brown through art.

The 19-year-old singer was spotted doing some street art in Colombia and gave the fellow singer (and graffiti artist) a shout out in his designs. Inside of a pink arrow, Bieber spray-painted the words "Free Breezy" in red, referring to the 24-year-old Brown voluntarily checking into rehab for anger management on Tuesday, Oct. 29.

Bieber's fun that night was shared with R&B singer Khalil, who Instagrammed a picture of "Me & Bizzle trying something new." Bieber, who was in South America for his Believe world tour, also uploaded photos of his artwork. He spray-painted "RIP PAC," a tribute to his pet hamster he named in the late rapper's honor.

"[L]ong night last night. good times. off to another show," he tweeted earlier Thursday, before performing in Ecuador later that night.

An article on Bieber's street art in El Tiempo cited Police Director Rodolfo Palomino saying, "We have to evolve. Graffiti is an expression of a feeling, motivation."

Brown entered rehab "to gain focus and insight into his past and recent behavior," the singer's representatives said on Tuesday, after he was arrested and charged with assault over the weekend. The Fine China singer pleaded not guilty on Monday to misdemeanor assault after police reports said the he and his bodyguard punched a man in the face outside a Washington hotel. He is due back in court on Nov. 20 and faces a maximum of six months in jail and a $1,000 fine if convicted.
