Kris Jenner will do anything to make her children happy, even if it means she has to splash her cash. The 61-year-old reality TV star has reportedly hired expensive lawyers to fight Blac Chyna for the custody of Dream Kardashian, Blac's daughter with Rob Kardashian.

OK! reports that the momager has "hired a crack team of the most brutal blood-thirsty lawyers money can buy" to get her only son full custody of Dream. "She is NOT letting Chyna get away with it and she fully intends to have her go away amicably and leave Dream with Rob," sources tell the site.

The so-called insider add, "Kris has more than expensive lawyers up her sleeve too - she knows Chyna wants fame and Kris holds the key." Though Chyna may "try and swindle the family with threats of tell-alls and spilling secrets," Kris won't be easily scared.

"She's no match for Kris Jenner," the sources say of Blac, who also has a 4-year-old son, King Cairo, from her relationship with rapper Tyga. She's "fought off countless gold-diggers on behalf of her kids," the sources add.

Despite the alleged fight over full custody of Dream, Rob and Blac remain to be friendly. In late May, the sock designer posted on Instagram two throwback photos of his baby mama. "On my first episode of Rob's Random Cornball Thoughts is This young lady who grew up to be the woman I love and the mother of my child," he wrote in the caption of one of the old pictures. "She is beautiful and gave me my first child. @blacchyna."
