Los Angeles can tick off Sabrina Carpenter singing with Christina Aguilera from their Christmas playlist. At Friday night’s Short n’ Sweet concert at the Crypto.com Arena, Aguilera joined Carpenter song “Ain’t No Other Man” and “What a Girl Wants”, presumably as a consolidation prize for setting foot in a place called the Crypto.com Arena. Aguilera burst onto the stage wearing knee-high boots almost as sparkly and tall as Carpenter’s, and the two began belting out the tracks. Last month, the two recorded a duet of “What a Girl Wants” for Spotify; it was a major milestone for Carpenter, as she is in the past said Aguilera was the first artist she fell in love with. And after scoring 6 Grammy nominations last week, it’s just proof that it’s Miss Polly Pocket’s world and we’re just living in it.
