Former first lady Michelle Obama posted on Instagram a comedic, text exchange she had with her mother following the Grammy Awards.

Obama made headlines on Sunday when she made a surprise appearance at the Grammys, joining the stage with host Alicia Keys, Jennifer Lopez, Lady Gaga and Jada Pinkett Smith. The group was on-hand to talk about how music has affected their lives and the world for the better.

Obama's mother, Marian Robinson, texted her asking if she had met any "real stars" while attending the ceremony and said that Obama did not tell her about the appearance in advance.

Obama replied to her mother and said that she is a real star.

"When your mom doesn't think you're a "real" celebrity," Obama captioned the images of the text conversation.

"I shared this text thread from my mom from #Grammys night, and I just had to share it with all of you. #TextsFromMom," she continued.
