The music video for "Celebrate" was filmed on May 30, 2012. The video was shot over two days in down town Los Angeles and is directed by Marcus Raboy. A preview of the video premiered on Entertainment Tonight on June 4, 2012. The music video made its world premiere on BET's 106 & Park on June 27, 2012. The music video treatment originally was set to include both Sparks and Houston, But with her unexpected passing in February 2012 before the video was shot the treatment had been changed. Sparks says "When we did the song, we planned on it being Whitney and me. But she's not here, so we wanted to make it a tribute to her. So it's fun, upbeat and exciting — there are clips from the movie and the main cast is in the video too. It's me, Tika Sumpter, Carmen Ejogo, Derek Luke, Omari Hardwick ... Goapele is in it and Mike Epps. We're all just having a good time [and the premise is] they all come over to my house singing along to Whitney's music. And we're missing her and celebrating her as well. It's actually pretty simple, but when you watch it and hear her voice along with it, it makes it so much more."
Sparks hosts a house party at her place with fellow cast members of Sparkle in attendance. Throughout the video, Footage from Sparkle, mainly focusing on Houston, is spliced in throughout the clip. Houston's scenes in the music video show the late singer in her acting prime as she smiles in many of the clips then cries in another. The final shot of the music video is an image of Houston from the film. “Celebrate” is dedicated to Houston's memory.
The video was met with positive reception. Rebecca Ford of TheHollywoodReporter.com calls it "a very positive and uplifting video". Sabrina Rojas Weiss from VH1 said "For a while now, we’ve been thinking of Sparkle as “the movie that makes us really sad about Whitney Houston.” We probably weren’t alone". She concluded "which is why the release of the video “Celebrate” was a brilliant move". Tanner Stransky of Entertainment Weekly praised the video saying "It feels triumphant, in a way, that they carried on [The Video] without Houston". Byron Flitsch from MTV.com says "we're really loving is the storyline that weaves in a montage of movie scenes" he went on to say "it's the emotional, almost home-movie quality honoring Whitney's on-screen presence that gets us all kinds of sentimental".
