"Who is coming to see us???" she wrote as the mommy and daughter both made faces feigning surprise.

Jamie Lynn's older sister, Britney Spears, also melts a little when she sees her adorable niece.

"How cute is Maddie watching mom rehearse?" she asked in posting an image to Instagram last week before wishing her sister good luck at the CMA Fest, adding. "Wish I could be there!"

CMA Fest airs on Aug. 4 on ABC.
