Kylie and Dannii recreate infamous Dynasty catfight for TV special

It is one of a series of sketches that make up an ITV special to be screened on Saturday night.

The pop princess also reunites with former boyfriend Jason Donovan and dons the trademark dungarees and perm hair-do which launched her into the public eye as Charlene Mitchell.

TV viewers will see Donovan send himself up and pretend not to know who the pop princess he once dated is during The Kylie Show on ITV1.

Kylie and Jason's appearance together takes place 20 years after their on-screen Neighbours wedding was one of TV's biggest events.

In another scene Kylie - dressed as a grown-up Charlene - appears slumped on the floor with smoky eyes and surrounded by bottles.

The sketches in the 60-minute show have been penned by George Jeffrie and Bert Tyler-Moore, the writers of Channel 4's Star Stories.

The marriage of tomboy mechanic Charlene Mitchell and boy-next-door Scott Robinson was broadcast in Australia in 1987 and a year later in the UK.

But Minogue left Donovan devastated when she ended the relationship in 1990 and began her affair with INXS star Michael Hutchence.

Minogue went on to become a huge star, shedding her squeaky clean image, while Donovan's pop and musical career collapsed and he turned to drugs.

Donovan, 39, now a father-of-two, made a comeback after appearing in last year's series of I'm a Celebrity... Get Me Out of Here!

In Saturday night's ITV show, Donovan thinks Minogue is a fan who wants his autograph.

He signs her script before Minogue, 39, reminds him of their Neighbours history and that they dated for years in real life.

Neighbours actors Blair McDonough, who plays Stuart Parker, and Jonathon Dutton (Wayne "Tad" Reeves) also join Minogue.

Donovan recently admitted in his autobiography that his jealous outbursts ruined their relationship.

"Kylie's star started to shine and I did the chasing - and I slowly lost her," he said.

Mechanic Charlene quit the soap in 1988, before Donovan followed.

Their 1988 duet together, Especially For You, became a huge hit and went straight to Number One in the UK pop charts.

The BBC recently dropped out of a bidding war for the soap, which will be screened on channel Five.

The Kylie Show, in which Minogue also performs on a bucking bronco, is broadcast at 9.35pm on Saturday night on ITV1.
