Justin Bieber has slammed celeb news outlet Hollywood Life for being complete "garbage".

The 21-year-old Baby singer reunited with his ex-girlfriend Selena Gomez earlier this week at a church function hosted by Pastor Rich Wilkerson Jr.

Hollywood Life published a news story with the headline reading 'Justin Bieber & Selena Gomez: Why Their Church Believes They Should Be Together' on Thursday May 28, and Justin is outraged by the article.

"HOLLYWOOD LIFE IS THE MOST OUTRAGEOUS FAKE WEIRD NON FACTUAL GARBAGE WEBSITE IVE EVER SEEN (sic)," he wrote on his Instagram account Friday, attaching a screenshot of the headline.

The star went on to explain why he felt so compelled to speak out against Hollywood Life's article.

Justin has advised fans to steer clear of the outlet's website due to the story, which he considers completely bogus.

"THEY LITERALLY MAKE UP WHATEVER THEY WANT AND USUALLY I DONT CARE BUT THIS ONE IS SO RIDICULOUS I HAD TO SAY SOMETHING DONT GO TO THEIR WEBSITE AND GIVE THEM ANY TRAFFIC (sic)," Justin wrote.

His and Selena's midweek reunion literally set the Internet on fire.

But according to TMZ, the pair will not be reuniting romantically anytime soon, as they were simply at the event to show their mutual support for Pastor Rich Wilkerson Jr.

"They are definitely not back together whatsoever," a source told E! News of the former couple's encounter. "Definitely not."

Apparently the pair, who dated on-and-off from December 2010 until last year, ran into each other unexpectedly.

"For the first time, it wasn't awkward," the source noted. "They were cordial and friendly to each other. It was harmless."
