There’s a bit of good ol’ fashioned feminine rivalry going on between ball player Alex Rodriguez’ former fuckbag Kate Hudson and his current piece of ass, Cameron Diaz. According to Page Six:

“Kate hates Cameron,” an insider [says]. “She’s pissed Cameron is dating A-Rod.”

Hudson’s convinced Diaz is striking back at her, because [she] hooked up with Justin Timberlake in 2007 — only days after Diaz ended a four-year relationship with him.

“Kate thinks it’s payback, pure and simple,” the insider [revealed]. But things have been tense between the women for some time. Hudson has been happy to remind pals that she scored a coveted spot in the musical “Nine” that Diaz had craved.

“Kate thinks Cameron is an aging old-lady actress struggling to remain sexy and relevant,” a source close to Hudson said.

A pal of Diaz’s scoffed, “Kate is only upset because she hates being single.”

And then Kate was all, “Well, I’m rubber and you’re glue, and whatever you say bounces off me and sticks to you, so you should shut your stupid mouth.” And then Cameron was all, “Why doncha make me?” And then Kate goes, “Sorry, I don’t make trash, I burn it” and Cameron goes, “Well, I don’t shut up, I grow up, and when I look at you, I throw up!” and everyone in Mrs. Kimball’s fourth period Earth Science class agreed that Kate got totally owned.
