Four tune up for 'X Factor' semis

The last four 'X Factor' hopefuls go into action again tonight as the show reaches its semi-final stage.

Olly Murs, Danyl Johnson, Stacey Solomon and Joe McElderry are still in contention on the ITV show, with the winner chosen next weekend.

McElderry is favourite with a range of major bookmakers.

The final four clash at the end of a week in which Johnson claimed Whitney Houston “absolutely hated him” for singing one of her unreleased songs on the show.

The 27-year-old teacher said the American pop star, who mentored the contestants for one week, disliked him for singing 'I Didn’t Know My Own Strength', which is yet to be released in the UK.

Asked which was his least favourite celebrity guest on the show, Johnson said: “Whitney absolutely hated me.”

He then added, sarcastically: “She loved the fact I was singing a song she hadn’t released yet.”
