Celine Dion makes surprise appearance at Adele's Las Vegas residency

What Happened: Celine Dion at the Event

While performing 'When We Were Young' at her Caesars Palace residency, Adele spotted Celine Dion in the crowd, walked into the aisle and embraced her. Adele later wrote on Instagram that she touches a photo of Dion next to the stage before each show because the Colosseum was built for Dion. Adele was reduced to tears.
