Verdict: Five stars.

IMPRESSING The King's Theatre audience has become a bit of a 'habit' for singer Alexandra Burke.

For last year she put on an effortless display as Rachel Marron in The Bodyguard Musical.

And now she's upped the ante by taking on a risky comedy role as Deloris Van Cartier.

In a role made famous by veteran comic Whoppi Goldberg, Burke brought a new dimension to the character making her sassy, sexy and most importantly funny, and those qualities were bolstered by a supporting cast who were simply outstanding.

The plot pretty much stays true to the 1992 hit movie about singer Deloris Van Cartier witnessing her lover murder a man.

She runs off to the police who place her in witness protection in a place most would not think of - a convent.

And this is where the real comedy begins.

Directed by Strictly favourite Craig Revel Horwood, the show contains an original musical score.

Fans of the movie might be disappointed to learn there is no Mary Well's My Guy nor does the stunning I Will Follow Him make an appearance.

But the music although brand new instantly connects with audience which is a rarity in a show still in its infancy.

It's upbeat, soulful and catchy.

And most importantly for this production of Sister Act, Burke's voice has the capacity to deliver the songs the way they were to be.

The script is hilarious with the cast's comic timing spot on.

Each of the nuns are very funny in their own way, and the audience was in stitches relating to their quirkiness.

This must seen musical performance was set against an authentic backdrop that made you feel like you were in church.

The production even had church acoustics in place to add to the authenticity.

Musical theatre fans are always wary of productions which are based on a movie.

But Sister Act is one of the few that pulls it off.

The musical might even be funnier than the original movie - and that's saying something.

Catch Sister Act The Musical at The King's Theatre until Saturday.
