James Corden followed Beyonce’s visually stunning performance at the Grammy Awards with a “Carpool Karaoke” bit on the floor of Staples Center that gathered a small crowd of music stars — but it was little Blue Ivy Carter who stole the scene.

Corden stepped into a giant cardboard cutout of a compact car as he gathered Jennifer Lopez, Tim McGraw, Faith Hill, Keith Urban, John Legend, Ryan Tedder, Jason Derulo and Neil Diamond in the aisle for a rousing chorus of Diamond’s “Sweet Caroline.” The bit was clearly planned, but about halfway through young Blue Ivy Carter ran up to join the group in a moment that seemed genuinely impromptu.

Carter was sitting in the front rows of the arena and had just finished watching her expectant mother’s show-stopping performance of two selections from “Lemonade,” complete with an elaborate hologram introduction.

Wearing a pink tuxedo with white ruffle blouse, she looked like any other 5-year-old goofing around with adults at a party — except in her world, the party happens to be the Grammy Awards. Blue Ivy turned 5 on Jan. 7.
