We're right behind you all the way!

Local support for X Factor stars Sarah and Sean Smith is reaching fever pitch as the duo prepare for tonight's live performance.

Youngsters have created a huge Same Difference banner while Pompey have asked the pair to sing during half-time against Derby in January.

The duo from Widley have also been invited as special guests to the famous Mad Hatter's Christmas Tea Party in Portsmouth, for children suffering from cancer or long-term illnesses and disabilities.

Sarah, 19, told The News: 'To get all these offers is amazing.

'At the moment, everything is depending on how far we can make it in the competition but if we can come we would love to give the kids an amazing Christmas present.'

Their home city of Portsmouth has got behind the brother and sister act with posters put up in hundreds of windows.

Eight-year-old Lauren Murray was so desperate to support the pair she made a huge banner with the help of fellow youngsters from across Portsmouth.

It was put together by children attending Portsmouth's Children University Scheme, where Lauren's mum Shelley, 35, teaches.

She said: 'As you will see from the banner, the girls in the class spent most of their day, creating designs and personalised this for Sean and Sarah.

'They loved it.'

Sean is excited about the possibility of singing live with his sister on the hallowed turf at Fratton Park.

The club have invited the pair to perform during half-time at the Derby game on Saturday, January 19.

Sean, 22, said: 'That would be a dream come true.

'I remember watching them when they were in the old Division One, sitting on my dad's shoulders because I couldn't see.

'I just hope the fans don't give us any stick for being cheesy but I'm sure they'll get behind us.'

Tonight's X Factor theme is love songs.

Same Difference said they have stripped out their usual cheesy dance routines and are determined to show people they can sing.

Sarah, 19, said: 'We really want our voices to come through.

'The song is very famous and is a rock ballad from the 1980s.'

This week's show will be on ITV1 tomorrow from 6.40pm.
