Kanye West admires Caitlyn Jenner.

The 'Bound 2' rapper is reportedly very fond of his mother-in-law, who was known as Bruce Jenner before undergoing a gender transition.

A source said: ''[They] have gotten very close and trust each other implicitly, they've bonded over a lot in recent weeks. [He] admires [her and] the fact she stuck around so long in a truly awful environment.''

The 38-year-old star is reportedly getting tips from Caitlyn on how best to ''stay sane'' when surrounded by Kanye's wife Kim Kardashian West, her sister Kourtney Kardashian and Caitlyn's ex-wife Kris Jenner.

The insider added to US' OK! magazine: ''Kris, Kim, Kourtney and co. breathing down your neck all day is anyone's nightmare - and Kanye has been milking Caitlyn for advice on how to stay sane.

''[She told him to] stick up for himself on a day-to-day basis.''

Meanwhile, the 34-year-old television personality recently insisted the ''whole family'' were supportive of Caitlyn's gender transition.

She said: ''No matter what, we love [Caitlyn]. I know [she] feels great that [her] whole family does support [her].

''I feel for people that don't have that support. There's such a high suicide rate in the transgender community, which is heartbreaking.''
