Caitlyn Jenner is tying the know again! This time (and for the first time as a woman) Jenner is marrying transgender student Sophia Hutchins. Things have developed quickly despite the 47-year age gap - Jenner is 68 and Hutchins is 21. The couple claimed to be just "friends" and have a close "mother and daughter" relationship. Either their relationship grew or they wanted to throw the press off; either way Caitlyn and Sophia are planning an intimate ceremony at Jenner's Malibu estate.
