Kylie Jenner is a spokesperson for the direct rival of Kanye West ... PUMA.
It's a stunning development ... because remember, just a week ago Kanye tweeted, "100% there will never be a Kyle PUMA anything."
We're told Kylie will be in the Spring/Summer women's training campaign, which launches in April.
PUMA says Kylie represents, "a fresh and exciting new era for fashion and we couldn't think of a more fitting and influential female to headline this campaign."
Remember, Kyane called out PUMA, telling them, "PUMA, we gone give you your measley million dollars back!
