Is it appropriate to go to a top level manager in your company whom you admire and ask them to mentor you?

My boss’s boss has taken a liking to me and I like her as well. I admire her attitude towards work and life along with her successes. This woman is amazing at what she does. She says she sees leadership qualities in me and wants to “groom” me to move up within the company. I see her as sort of a mother(ish) figure who has a lot of insight to share with me about the job. She has an open door policy and is friendly with all my colleagues. But, is it cool to go to her and say something along the lines of, “Hey, I admire you and want to learn more from you”? Surely she has enough to do managing our office.

I also realized after proofreading this question that it comes off as totally creepy, but I swear, it’s not!

Hoping to get some advice from some of you with more experience in the corporate world… or working for the man. However you like to put it ;)
