Boyfriend cheats on Alexandra

VOICE of Ireland organisers have confirmed that singer Alexandra Burke will appear on the show on Sunday.

Alexandra (below) was today dealing with claims that her England soccer star boyfriend Jermain Defoe cheated on her with a model.

Defoe (29) and Alexandra (23) were slow to go public with their romance, but the singer has appeared smitten in recent weeks.

Now the singer's world has crumbled as a model who befriended Jermain on Facebook has now said that they had sex.

Alexandra, who was due to appear on the Sunday night show, wore a 'Defoe' shirt for a volleyball game in the Caribbean earlier this month.

Sources close to Alexandra are not surprised she's sticking to her schedule. "At the end of the day she's a true professional," the source said.
