As the rumor mill continues to churn over the reasons behind Bruce Jenner's recently altered appearance, an insider tells Hollywood Life that Jenner's granddaughter, North West, seems confused about her grandfather's gender.

Assuring the tabloid that Kim Kardashian and Kanye West "don't have an issue at all with how Bruce looks," the source notes that, "They feel he's an adult, an accomplished Olympian and one hell of a father. They're not embarrassed at all and they feel he's comfortable in his own skin."

However, the snitch claims Kimye are somewhat concerned about daughter's impression of Kim's dad.

"The problem or concern they have is for North," the source says, according to Hollywood Life. "She sat on his lap not too long ago and said 'mama.' She doesn't know how to say boy or girl or man or woman and refers to both men and women as 'mama' or 'dada' and she called Bruce 'mama.'"

The chatter surrounding Jenner's changing looks began after he reportedly underwent a procedure to shave his Adam's apple, which is often part of the path towards sex change surgery (Kris Jenner has dismissed rumors that her ex plans to become a woman). The Olympic veteran recently debuted a new coif of longer, light brown locks.
