If there’s one thing Paris Hilton is always gonna ride hard for, it’s her pal Britney Spears … and she made that crystal clear, calling her an “infinite icon” during a chat with us.

We caught up with the mega-socialite in NYC Wednesday, and Paris had nothing but love for Brit … gushing about her strength and basically telling fans to relax, because Britney will forever be that girl.

Watch the video … Paris went full serious mode, praising Britney’s massive heart and declaring we’re all lucky to have her.

And as a mom herself, Paris also weighed in on Britney reconnecting with her sons … serving up even more love and support.

Sure, we all know Paris for her fun, bubbly vibe, but this convo went deeper — touching on the topic of her ADHD “superpower” — so don’t miss the full clip to hear it all straight from her!
