Celebrity Big Brother housemate Ivana Trump has been duped into thinking she has won a fake award.

The socialite ex-wife of American business mogul Donald Trump was called to the Diary Room this morning and told by Big Brother that she has been nominated for the Best International Businesswoman On A Reality TV Show award by the readers of Scandinavian magazine Kugel Fresh, and must prepare an acceptance speech to give via satellite in English, German and Czech.

Meanwhile, the other celebrity housemates were gathered on the sofas and informed by Big Brother that the ceremony is fake, but they must convince Ivana it is genuine in order to pass their task and win an awards party.

Once Ivana has made her speech, the housemates also have the task of telling her the award looks stupid, attempting to drink from it, and breaking the trophy, all without her suspecting anything.

Former Olympic skiing champion Ivana, 60, has asked the other housemates to help her with her speech.

The Czech celebrity will give the speech from the Diary Room and the other housemates will watch on a screen in the living room.

The other celebrities congratulated Ivana on the award win in the bedroom.

As she went for a shower to get ready for her appearance at the awards, footballer turned actor Vinnie Jones told Stephanie Beacham: “Dane thinks they’re going to keep giving us things to do so let’s just leave it now. That was a bit over the top.”

Stephanie said: “It’s not more than I usually would have done, if it had been real.”
