Bruce Jenner transgender rumors continue to circulate, and his sons Brandon Jenner and Brody Jenner have reportedly stepped up to support the former "Keeping Up With The Kardashians" patriarch.

According to a report from Radar Online, the ex-husband of Kris Jenner is keen on transitioning to a woman. The former Olympian's adult children from his previous marriage are reportedly backing up their father's decision.

"It's obvious to anyone that he is struggling with gender identity issues," an insider pointed out, following paparazzi photos hinting at Bruce Jenner's transgender desires. Some of the images showed the reality star wearing lipstick, growing his hair long, and wearing nail polish.

"(It) didn't come as a surprise to the brothers, but they both feel it's very insensitive to the LGBT community," a source revealed about Brandon Jenner and Brody Jenner's reactions to the images.

"Both Brandon and Brody are both very strong supporters of LGBT people. They're standing by their dad through this."

In Touch also reported about Bruce Jenner's decision to become a transgender.

"(2015) will be the year of his coming out," an insider said about the 65-year-old's transition to a woman.

"He knows that people have recognized his changes, and he's finally becoming more comfortable with himself and his choice to become a woman."

The In Touch report also detailed Bruce Jenner's "big reveal" plans.

"When Bruce goes public, he wants to go big and come out as a transwoman on the cover of The Advocate, the ultimate LGBT magazine," the source claimed.

"He wants to look as glamorous as possible- full makeup with a bold wardrobe."

Radar Online reported that Bruce Jenner's transgender announcement has the blessings of his sons.

"Brandon and Brody will continue to support their dad, and if does indeed, make the transition to being a woman, their feelings for him won't change," an insider said.
