Amanda Holden is pumped up for Britain's Got Talent (and no, we're not talking about her lips)

Earlier this week the size of Amanda Holden's lips aroused suspicions amongst some observors, but whether or not she's had them cosmetically enhanced remains a mystery.

However, on tomorrow's Britain's Got Talent she'll be hard pressed to deny that there are at least a few things on her that have been pumped up.

In this case though the talent show judge is merely made to wear some colourful balloons that have been expertly moulded and shaped during the auditions in Newcastle.

An amusing act, cleverly named the Balloon Brothers, transform the actress into a fairy with the aid of their moulding balloons.

She joins the twosome on stage, where she plays along as their assistant before being given a pair of wings, a wand and a tiara...all made from balloons.

Unaware of what the Durham duo are doing, Amanda initially sports a confused look on her face as they kit her out in the pink balloon ensemble.

However, once she realises that they are making her into a cute sugarplum fairy she wears a beaming smile, before returning to join Simon Cowell and Piers Morgan on the judging panel.

The twosome, Keith Stirman and Dominic Cassidy, make their intricate creations while playing music from the Blues Brothers movie.

They arrive on stage in a police car made entirely from balloons before calling Amanda up on to the stage.

After their act they head backstage to make Stephen Mulhern a jet pack he's always wanted.  

Actress Amanda Holden also likens Simon Cowell to the Prime Minister during a chat with Stephen.

She tells him how much she loves working on Britain's Got Talent, explaining that a particular perk is flying round the country on Simon's private jet.

Stephen asks Amanda what the three judges talk about on the plane, she tells him: 'He (Simon) really does talk very openly about everything, his private deals he's doing, his American shows.  

'I just sit there thinking, this is unbelievable...It's kind of like being with the Prime Minister.  He's right at the centre of show business, he is the person that everybody wants.'

Stephen also falls foul of Piers Morgan when he wipes gold paint on the judge's £2000 suit.

After lending a helping hand to paint a naked model he bumps into Piers backstage and manages to wipe gold body paint all down the arm of Piers suit and across his face.  

A few days later Piers is seen re-telling the story to Amanda, whilst Stephen is there.

He tells her: 'Do you know how intelligent Stephen is? He covers his hands in gold paint, comes up to me and goes "Alright mate" (wiping hands down his arms) ruins my suit, goes "Alright son" (wiping his hands on face). Ruins a £2000 suit and covers my face in gold paint.'

As well as the Balloon Brothers and the naked model, viewers can expect to see another dog with talent this week as a pooch takes to the stage to play his owner's guitar.
