In a matter of minutes, fans began commenting on the picture and accusing John Legend's wife of expecting more than one child.
"Uh @ChrissyTeigen from the looks of that bump, I think u might be expecting twins!! Isn't it kinda early to be already shown like that?" one follower tweeted. Another added, "@ChrissyTeigen you got big fast! My bestie is due in Feb and she's ½ your size. Not twins? Probably triplets."
