Bruce Jenner's daughters are "confused" by his current appearance.

The reality star has recently undergone a laryngeal shave to make his Adam's apple smaller and is sporting dyed hair with highlights and longer nails, and his daughters Kendall, 18, and Kylie, 16, with estranged wife Kris Jenner don't understand the new look.

"Kylie and Kendall just don't know what to think. It's extremely confusing for them to grasp. There is just no denying Bruce's recent physical changes, and he does look more feminine. It's been especially hard for 16-year-old Kylie because some of her friends have made jokes about Bruce's looks," a source said.

Kris has denied Bruce - who lives in Malibu, California, away from the family home in Calabasas - is undergoing a sex change and he has said he only had the throat operation because he didn't like the way his Adam's apple looked. "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," the source said.

The decision by Bruce, 64, to move out last year has been especially hard on Kendall and Kylie as he had always been there for them in the daytime, while Kris was concentrating on the careers of their half sisters, Khloe, Kourtney and Kim Kardashian. "They have always been closer to their dad because Kris had been busy for so many years with their older half-sisters. It was always Bruce driving the girls to and from school. He wants to spend time with them, but it's hard for them to get all the way over Malibu where he is living. Plus, they would much rather be with their friends, which is typical for teenagers. Still, they miss their dad," the insider added.
