Pratt and Jenner have been friends since the age of 13, but Pratt found another way to reach out to his pal on his big day

Many expected the longtime pals to make a splashy reunion at Jenner's union with Tia Blanco; however, Spencer Pratt was noticeably absent.

Spencer Pratt has explained why he missed Brody Jenner's wedding. Spencer and Brody shot to fame in the popular MTV reality show The Hills, which aired for six seasons until 2010, and the pair have remained good friends.
