The drama began when former ESPN reporter Bonnie Bernstein tweeted about the singer's low plunging dress -- saying, "Dear Ciara. You're stunning. But this is a National Championship Game. Kids are watching. Cover up."
The tweet started a firestorm on social media -- with everyone from Hugh Douglas to La La Anthony supporting the singer ... and ultimately Wilson decided to throw in his two cents.
"I see you baby!! Sounded amazing & looked flawless in every way! @Ciara"
Some people accused Bonnie of criticizing Ciara because she's black -- Bernstein responded to that too.
"Truly am amazed at how people take a tweet (that includes a compliment!) & wanna make it about race. Seriously. Grow up. Watch the game."
So far, Ciara hasn't responded to Bernstein ... but did repost a pic of her singing ... saying, "Truly Grateful For This Moment, and To Be A Part Of A Special Night."
