The commission follows the success of a non-broadcast pilot.
Production company Bullion filmed an initial episode earlier this year for BBC Three's Comedy Slices strand. It has yet to be published or broadcast, but - having seen the finished episode - the BBC's comedy commissioners have now given the go ahead to film a four-part series.
Wannabe sees Brazier - who plays Mich in People Just Do Nothing (pictured) - star as a former girlband member who decides to return to the business as a 'pop mum'. The BBC explains: "Back in the girl-power heyday of the 90s, a hit single would easily get you 15 minutes of fame. But 15 minutes just isn't long enough for some people...
"Maxine never made it to the big time as part of teenage girl group Variety and now, as a middle-aged failing music manager, she finds herself in crisis, when the one act she looks after threatens to drop her. But Maxine has come up with a plan. A come back. This time bigger, bolder and, well... older. Who cares about a hip young girl group anyway?! What the world is really missing, is Mum Pop..."
The pilot episode was written by Lily Brazier and Ben Murray and directed by Ben Murray and People Just Do Nothing's Steve Stamp. Nicholas Burns, Jim Howick and Ryan Molloy were amongst Brazier's co-stars, with Dane Bowers making a cameo appearance.
Speaking at the time the pilot was announced, Lily Brazier said: "Wannabe has given me the opportunity to finally live out my childhood girlband dreams despite my lack of dancing and singing ability. I'm really excited for everyone to see the little world that we've created with such an amazing cast."
The BBC comments: "Wannabe is the story of unfinished business, one last shot at fame and struggling to let go of a lifelong dream."
