John Legend Gets Upstaged by Chrissy Teigen, and She Wasn't Even with Him

So THIS might be what John Legend meant when he sang, "We're just ordinary people" -- 'cause without Chrissy Teigen, some photogs kinda treated him like a normie.

Kinda ridic when ya think about it ... the Emmy, Grammy, Oscar and Tony award winner was leaving Madeo Thursday night in Bev Hills, and the first question he got -- WHERE'S CHRISSY?!?!

Ya gotta watch the vid ... John's response is hilarious as a throng of paps are immediately deflated. It is true ... we're used to seeing the couple together -- almost always -- so forgive us, John for expecting to see your better half.

Luckily, he wasn't offended, and still shared his thoughts on Donald Trump and the release of the Mueller report.
