One of my favorite Mormon celebrities is Alex Boye. He is one of the featured people on the new Mormon.org site. You can find his bio at this link. There is also this article of him in the Church News.
Anyone who thinks "Mormons" fit a stereotype, will find themselves rethinking it after encountering Alex Boye. Below is his video profile on YouTube from Mormon.org. I don't think it is submitted by an authorized source though. The second video is my favorite. In it he identifies himself as a member of the Mormon Tabernacle Choir and introduces a new song he's selling to benefit a needy family. He doesn't swivel his hips but he swivels everything else. He's amazing.
