BLONDE BOOTYS!! Lala Anthony And Iggy Azalea . . . Show Off Their AMAZING FIGURES!!

LaLa and Iggy couldn't be MORE different . . . but they have a few things in common - their both BEAUTIFUL and they have amazing bodies.

LaLa spent yesterday promoting the upcoming season of the show Power. She took some time of from promo to make sure that she went to the wake for the deceased 15 year old named JUNIOR that was murdered in the Bronx, New York.

LaLa and her husband Carmelo Anthony have pledged to do everything possible to help bring Junior's kilers to justice - and to keep his memory alive.

Iggy was on a Hollywood set, filming an upcoming music video in Los Angeles.

TMZ reported that, La La Anthony says meeting with the family of Lesandro Guzman-Feliz (the boy dragged out of a corner store and murdered) was "super emotional" -- but now she wants justice.

As we previously reported, La La and Carmelo Anthony met with the 15-year-old boy's family to help console them after the senseless stabbing. La La was told Lesandro (aka Junior) was a huge Melo fan.

"I have a son and that story really touched me," La La tells TMZ Sports ... "I wanted to do something to make a difference."

So, what now? La La says the mission is simple -- "We want justice for Junior."

"I just want his family to have some kind of peace."

So far, cops have arrested 8 suspects in the slaying -- alleged gang members -- and Junior's mother has called for all of them to get life in prison.

Cops say the alleged killers had mistaken Junior -- a member of the NYPD's police explorer program -- for someone else.
