The 72-year-old singer took out a full-page ad in The Hollywood Reporter congratulating the "Black-ish" star on her nomination in the category of Lead Actress in a Comedy Series.

Tracee, 43, reacted like a typical daughter, tweeting a screenshot of the ad on Tuesday, and commenting, "OMG how cute r my mom @DianaRoss & family 4 taking an ad in @THR."
