Deborah Cox finds herself front and center of a new social media challenge that's been all the rage ... and so far, she's impressed by what she's seeing.
The Grammy-nominated singer tells TMZ ... it's been extremely challenging figuring out who has totally nailed the "Deborah Cox Challenge" ... but if pressed, the award so far goes to 11-year-old aspiring singer Liamani Segura, whom Deborah says blew her away.
A little backstory ... the so-called challenge started on September 21 when an Instagram account dedicated to showcasing singers asked fans, regardless of talent, to try and sing Deborah's 1998 classic hit, "Nobody's Supposed to Be Here." Tons of celebs have done just that ... from Lizzo to Keke Palmer.
