A bout of stomach flu has swept through the Strictly Come Dancing camp – leaving dancers worried about being sick on set, according to the papers.

The Sun reports that Alesha is the only contestant not to have been hit by the bug – which struck down Letitia Dean last week and left her needing a bucket on standby in the studio.

“Tish was so ill and now everyone else is feeling the pain,” a source told the paper.

“They’re all worried about being sick tonight so it’ll be buckets on standby.”

Letitia was in the bottom two last week but was saved by the judges, and will compete in Saturday’s semi-final along with Alesha, Gethin Jones and Matt Di Angelo.

Meanwhile, Matt and his dance partner Flavia have admitted they have formed a close relationship during the series. “We definitely do have chemistry,” Flavia said.

“We’ve formed a really good friendship and that’s helped us through the competition and made the hard work easier.”

Matt added that losing Flavia will be “like a divorce”.

“It’ll be a sad day when I don’t dance with her,” he confessed.
