'KUWTK' Kendall, Kylie Jenner On Opposing Kickball Teams For Chris Brown Charity: Kendall Chummy with Kim Kardashian Ex-BFF Paris Hilton, Also In Attendance (PHOTO)

Sisters Kendall and Kylie Jenner were on opposing kickball teams for Chris Brown & Quincy's Kick'n It For Charity event in Glendale on Saturday. All proceeds benefitted Symphonic Love and Best Buddies.

18-year-old Kendall played on Brown's team while her 16-year-old sister played for Team Quincy.

While the game went off without a hitch, there may some drama off the field involving Keeping Up With The Kardashians star and Kendall's big sis, Kim Kardashian, who is currently vacationing in Mexico with hubby Kanye West and daughter, North.

Kendall was seen being quite friendly with Kim's ex-BFF heiress Paris Hilton, at the event in Glendale on Saturday.

Friends since childhood, Paris and Kim's famous feud began in 2008 when Kim's star started to ascend and eclipse Paris'. Paris started taking cheap shots at Kim publicly saying in a 2008 radio interview, "I would not want [Kim's butt] - it's gross! ...It reminds me of cottage cheese inside a big trash bag."

There was notable fury over Paris' comments (moms Kris Jenner and Kathy Hilton are also pals) and she apologized by saying, "I was just joking around and I made a stupid joke, I felt really bad afterward, so I contacted Kim and apologized. It was a silly thing to say. Kim's hot!"

Kim appeared to have taken things in stride and accepted Paris' apology, "Paris and I have been friends since we were kids and I'm glad she made the effort to say she's sorry."

Or did she? Despite that apology, things were never the same and the girls parted ways by 2009.

On the field budding model Kendall stood next to Paris laughing and smiling. There is no doubt this will raise Kim's ire.

We also have to wonder, how did Kylie play kickball in those boots?
