Sisters Kylie and Kendall Jenner went head-to-head on opposite teams at Chris Brown’s charity kickball game this weekend!

The sisters were on opposite sides of the pitch when they competed for Chris and Quincy's 'Kick'n It For Charity' event in California yesterday.

Kendall was on Rihanna's ex Chris' team while Kylie played for Quincy's side. 

All proceeds went towards Symphonic Love and Best Buddies.

But what were they wearing?!

Kendall wore some killer combat boots while her younger sister donned a pair of thigh-high heeled boots – for kickball Kylie?!

The girls posed with Quincy and Chris – who was recently released from jail – for an Instagram snap.

Hmmmm….we hope protective dad Bruce is OK with all of this!
