Bruce Jenner has been filming a reality show about his "life changes," TMZ reports.

The show will reportedly run on E!, which also airs "Keeping Up With the Kardashians," about his famous family.

A rep for E! told FOX411 they were not commenting on the report.

Jenner's stepdaughter Kim Kardashian said Jenner is currently involved in a personal "journey," adding she has never seen him more happy.

TMZ's source said Jenner's interactions with his family will be part of the show, and that at one point in the filming, his now ex-wife Kris, "lost it."

The gossip site reported Kris will have little control over the former athlete's show, and he has taken control over the production and air date. 

Jenner's changing appearance over the past year-or-so -- long wavy hair, lip filler, fingernail polish -- have sparked numerous tabloid reports he may be transitioning from a man to a woman.
