Undercover Adele pranks impersonators

The second she started singing, they knew. But it was a good while before these Adele impersonators realized they were kickin' it with the real Adele.

With a fake nose, fake chin and not-the-usual-Adele makeup, the pop star transformed into a nanny named "Jenny" and headed off to an audition — to impersonate herself.

She chats with a group of clueless impersonators about how long she's been in the impersonation market — four years — and how business is going — pretty slowly, "there's not much of a demand."

"I can't wait for the new album ... new music," one impersonator says to the group. "She's taking her time," the real Adele cracks.

The impersonators' responses when they realize who Jenny really is? Priceless.
