Paladin Shining Knight "Skilled Rider" ablility question

[Jadenwolf]

Hey all, this is my first ever post! As stated in the title of the post, I have a question about the variant ability "Skilled Rider" presented in the APG. The ability states that "any mount she is riding gains the benefit of her divine grace class feature, adding her Charisma bonus (if any) to its saving throws." My question is this: does the mount use the paladin's charisma modifier or its own?

Thanks in advance...

Uses the Paladins, "her" is refering to the one who ability it is.

(Read: Her divine ability, Her charisma, its bonus)

otherwise it would be her divine, its charisma to its bonus
