Justin Bieber has had us patiently waiting for his new single to come out for a month now, getting pretty much every celebrity involved in the promotion process. The highly anticipated song "What Do You Mean" has finally been released and Bieber made sure to make the official release announcement with the help of some of Hollywood's biggest stars. I mean, what better way to celebrate the release of your new song than with Martha Stewart, Britney Spears and Ellen Degeneres?

After tons of celebrities helped Bieber countdown the days over the past month, he ended it with a bang. Last night, for the special "1 Day" left promotions, he had none other than his good friend Stewart and the Queen of pop herself.

"You know my girl @marthastewart had to be there," he captioned the photo of the 74-year-old business woman. Then, with just 10 hours left until the big moment, he got Spears to hold up her own "1 Day" left sign in front of her slot machines in Vegas. "10 hours to go Worldwide!" he wrote. "The amazing @britneyspears is excited :) #whatdoyoumean u ready?"

From then on, he counted down the hours on his Instagram until he could finally share his latest project, and he did not disappoint. The final promotional photo may have been the best one yet as Bieber stood holding his own "What Do You Mean" sign, looking flawless in black and white. "I'm back," he wrote, giving the Spotify link to listen to the song, which is already guaranteed to be a huge hit.

He then posted the lyric video, which is of his good friend pro-skateboarder Ryan Sheckler skating while the song plays in the background. To top it all off, he ended the whole thing with a video of him and Ellen DeGeneres dancing to the song in her studio as he kisses her on the cheek while she makes the final announcement that the song is now out. "Finally!!" he wrote. "#whatdoyoumean on @applemusic now. Let's take it to the top!! Good to be back :)"

Bieber will be performing the new song for the first time this Sunday August 30 at the 2015 MTV VMAs.
