Nikki, 23, was flown into the heart of the American Bible-belt region in Dallas, Texas, as part of a television debate with Ed Young, a famous American Baptist minister.

Mr Young, 47, is the son of another famous pastor, Homer Edwin Young, and founder and head pastor of the Fellowship Church, a so-called mega-church and one of the largest and fastest growing churches in America.

A reported 20,000 worshippers regularly visit the multi-site church, which follows the modern "seeker church" trend, meaning it tailors its services and programmes to attract non-church goers.

Nikki's agent Derek Hay, of La Direct Models, said: "Things went very well. Nikki was very confident, assured and, although not as articulate as a professional speaker like the minister Ed Young, she handled herself very well. She made several important and valid points, most pointedly on the issue of pre-marital sex."
