A man being held as a terrorist suspect in Britain is the half-brother of former supermodel HEATHER STEWART-WHYTE. The former face of Gucci, Versace and Armani was shocked when she heard DON STEWART-WHYTE, 21, was arrested on Thursday (10AUG06) as British police foiled an alleged plot to blow up passenger aircraft flying from the UK to the US. The 36-year-old mother of three and Don shared their father, late political activist DOUG STEWART-WHYTE - but Don changed his name earlier this year to ABDUL WAHEED after marrying a Muslim woman.
