Zendaya's Dad: She's Not Dating Odell Beckham ... 'It's an Audition'

This is one of the best clips EVER!!!

So, we spotted Zendaya out with Odell Beckham Jr. Monday night leaving a Grammy party together so we asked if they were dating -- and that's when HER DAD stepped in and explained ... "It's an audition!"

They were definitely acting coupley -- with the 23-year-old NFL star opening her door and walking her into the waiting SUV.

But when we asked Zendaya's dad if he approved of the relationship, he hit us with some of the realest real talk ever.
