Billionaire tycoon Donald Trump has added pressure to win his fight against World Wrestling Entertainment owner Vince Mcmahon - he's agreed to shave his famed bouffant if he loses. The Apprentice star has challenged MCMahon to a wrestling match in a bid to publicise each other's show. The men won't be the ones donning the spandex shorts though - each will be represented by their own handpicked wrestler, with the loser having to shave their head in the ring.
