Aubrey Anderson-Emmons – all of 5 years old – is barely bigger than the statue she'd later win Sunday night at the SAG Awards
But the girl who plays Lily on Modern Family
was right out there on the red carpet Sunday night, posing ever so delicately, almost too tiny for all the hoopla.
Backstage, after the cast won for best ensemble for a TV comedy, Aubrey's proud mom Amy Anderson told PEOPLE what went into getting the pint-sized actress ready for such a big night.
"She borrowed this dress from a neighbor," says Anderson. "The neighbor has a first-grader and she said she kept everything. I asked if she had a dress we could use for the SAG Awards. So she brought over a bunch, and [Aubrey] loved the ruffles."
