The footage ends with Jenny yelling, "Someone just played the piano", to husband Donnie Wahlberg, who appears to be in another room.

"Who?" he asks, prompting his wife to respond, "I don't know".

But the ghostly strains of the piano might not be such a big mystery - fans have taken to the comments section of her Facebook account to point out the chord played sounds very familiar to the sound a Google Home device plays when connecting.
