X Factor contestants Alexandra Burke and JLSs Aston Merrygold are struggling with throat infections.

Diana Vickers, Eoghan Quigg, Alexandra Burke and boy band JLS treated to competition winners to an excusive secret performance in the basement of a Carphone Warehouse shop in Oxford Street.

Both Burke and Merrygold are racing against time to get fit and healthy in time for their scheduled performances on Saturday night.

Reports claim that Astons voice has completely gone and he had to do a Britney Spears style mime at yesterdays gig where as Alexandra could only manage one song.

Bookies make Londoner, Alexandra Burke the favourite, something that scares her:

"It's very, very scary. I got that news yesterday. It actually shocked me as I wasn't expecting that." said the talented vocalist.

The four remaining acts go head to head this Saturday, with the overall show winner releasing Leonard Cohen's version of Jeff Buckley's Hallelujah before Christmas.
