Bruce Jenner has "embraced his old family and friends" since splitting from Kris Jenner.
The Olympic gold medallist's eldest daughter Cassandra Marino, 33, admits they have developed a closer bond since he and his third wife of 22 years announced their separation last October.
She told PEOPLE magazine: "He's really embraced his old family and friends that he hasn't seen for years. It's great."
Bruce also has a son, Burt, with his first wife and Cassandra's mother Chrystie Crownover, sons Brody, 30, and Brandon Jenner, 32, with his second wife, Linda Thompson, and daughters Kendall, 18, and Kylie Jenner, 16, with Kris.
Cassandra also discussed Bruce's recent decision to undergo a tracheal shave to reduce the size of his Adam's apple at a clinic in Beverly Hills and grow his hair longer, which friends claim is part of his desperate attempt to stay youthful.
She said: "It's his life, and whatever he wants to do, he wants to do."
She added: "He's always been a handsome guy, and he never needed to do anything. But you know, clearly he feels differently. And nobody knows how it is to be in his skin.
"If that's what he chooses to do, then I support him."
