Jason Donovan surprises Alison Hammond in BED in all leather look as she tells cameras to leave them to it during Michael McIntyre’s Midnight Game Show

Alison Hammond achieved her life-long dream as she ‘married’ Jason Donovan during Saturday’s episode of Michael McIntyre‘s Big Show.

This Morning host Alison, 48, was seen in bed with singer Jason, 55, as they emulated an episode of Blind Date with comedian Michael, 47, acting as the show’s late presenter Cilla Black.

Alison was in fact lined up to appear on Blind Date before she went into the Big Brother house in 2002 and ditched the opportunity to appear on the reality show which catapulted her to fame instead.

With a pink screen between Alison and Jason as they both laid on her bed at home after funnyman Michael paid her a visit for his show, Jason put on a fake accent and gave her clues to help her guess who it was alongside her.

Alison quickly correctly guessed and revealed she wished it was her who had married Jason when he played Scott Robinson in Australian soap Neighbours and his character married Kylie Minogue‘s Charlene Robinson in 1987, much to the amusement of viewers.

Many members of the audience at home took to social media to express their delight at witnessing Alison realising it was Jason in her home.

One person wrote on Twitter: ‘@AlisonHammond I’m sooooo jealous that you were in bed with the leather-clad @JDonOfficial!!! The perfect midnight treat!’

Another person wrote: ‘Jason Donovan in Alison Hammond’s bed is the best thing I’ve ever seen. God I LOVE Michael McIntyre.

While someone else shared: ‘#thebigshow LOL So, so funny with @AlisonHammond. Not laughed so much for ages… since last week’s show! Just what we need to get us through a dreary, grey winter. Well done @McInTweet You’re the king of Saturday nights!’

Another viewer posted: ‘The brilliant @AlisonHammond is just comedy gold.’

And someone else commented: ‘This was just THE BEST TV I’ve seen in a long long time!!! This was utterly brilliant and just totally lovely, fun and brilliant to watch!!! Awesome!!!!’

‘@MMBigShow Crying Laughing at Midnight game show! @AlisonHammond is an absolute legend! The girl’s a national treasure,’ wrote another viewer.

While someone else shared: ‘Alison Hammond on Michael McIntyre’s Midnight Game Show is a MOOD. I love her.’

After their Blind Date, Michael welcome Alison into his TV studio and gave her a framed picture of Jason as his Neighbours character Scott Robinson alongside his bride, Kylie Minogue’s character Charlene Robinson, at their 1987 show wedding, with Alison’s face superimposed over Kylie’s.

Alison was startled as Michael and his camera crew woke her up and ask her to take part in the fun game for his programme.

A stunned Alison asked Michael: ‘What time is it?’, to which Big Brother narrator Marcus Bentley, 56, appeared and told her: ‘I.30am’. 

Alison, who first found fame on Big Brother in 2002, said: ‘Marcus, hello Marcus’, before telling Michael: ‘I love this show. Babes, I’ve got no make-up on.’

To which he told her: ‘Don’t worry we’ve got a glam squad for you.’

Alison’s hair stylist and make-up artist then rushed in and gave her a 30 second makeover, while Marcus counted down the clock.

Last Saturday, viewers were left in tears after a huge US singer’s surprise appearance on the episode.

Singer LeAnn Rimes, 41, took to the stage and wowed audiences with her popular song How Do I Live alongside the ‘unexpected star of the show’.

This week the unexpected star of the show was mother-of-two and singing lover Sarah who in 2012 was diagnosed with a brain tumour.

On the show she thought she was attending a Country Western bar but actually took to the stage for Michael McIntyre’s Big Show, where she was surprised by LeAnn.

Her performance with LeAnn received a standing ovation, while many watching at home were left in tears.

One wrote in reaction: ‘Cannot lie, that duet with Sarah and @leannrimes brought a tear to my eye… some performance!’

Another penned: ‘Anybody else watching #MichaelMcIntyresBigShow and blubbing uncontrollably at the Unexpected Star,’ 

A third added: ‘Oh Michael @MMBigShow #Michaelmcintyresbigshow What a wonderful ‘star of the show, show’ with beautiful Sarah and @leannrimes. I’m still balling with emotion.’

Someone else posted: ‘Sarah was absolutely sensational! Best star of the show, show yet. And love Leanne Rimes! That should be released as a single with them both singing.’

After LeAnn wrote on Instagram: ‘surprise!!! after hearing Sarah’s story i started plotting with the @bbc and @michaelmcintyresbigshow to create a special moment that she would never forget. i’m not sure who cried more… if you missed it, you can watch our duet on @bbciplayer.’

Michael McIntyre’s Big Show airs on Saturday at 8.10pm on BBC iPlayer and BBC One.
