Bruce Jenner is eager to be a contestant on Dancing With the Stars.

The 64-year-old retired athlete, whose stepchildren Kim and Rob Kardashian have both previously competed on the reality series, is in talks to take part in the upcoming 18th season. "He's dying to do it. The show is close to locking him in," a source said.

Meanwhile, the Olympic gold medallist's sons Brandon and Brody Jenner are said to be very supportive of his recent decision to reduce the size of his Adam's apple. Bruce, who separated from his wife Kris Jenner in October after 22 years of marriage, reportedly underwent a "laryngeal shave" procedure in Beverly Hills on Sunday to soften the feature of his neck, which is typically done on patients who are in the first stage of gender reassignment.

"The boys don't think their father is trying to become a woman and simply laugh at rumors. They do believe that Bruce became more conscience of his physical appearance and how he looked after Keeping Up With The Kardashians premiered. They blame their stepmother [Kris] for all of the plastic surgery he has had over the years. Kris always encouraged Bruce to have his face nipped and tucked. He has had plastic surgery to remove excess fat above his eyelids. The Adam's apple surgery is just following in that pattern," a source said.

Bruce had cancerous cells removed from his nose in September and went under the knife in 2009 to fix a botched nose job and partial facelift he had in 1984, which was documented on his family's E! series.
