Lady Gaga’s appearance on Carpool Karaoke is definitely one of the biggest to happen since the segment started, possibly rivaling Michelle Obama or Adele in the status involved. The pink hat is here and it is alive and well the entire ride — and the rest of the show too. Before hitting the road with Corden, Gaga essentially took over the studio to do Corden’s opening for him and then join the band for the rest of the night. It is essentially a Gaga night on The Late Late Show, made a little ominous by the presence of Jeffrey Dean Morgan. He left the bat at home, but we all know what he did.
