's son is giving away the answer to one of the biggest curiosities surrounding his mom – is her thick Columbian accent fake?
Manolo Gonzalez-Ripoll Vergara, 19, developed what he calls, Mi Vida Con Toty
, a "documentary" about the Modern Family
star, 39, that he introduced on the YouTube channel
for Spanish web series NuevOn.
In the clip, Manolo says, "Something that many of you question all the time: her accent – is it real?"
He goes on to show an apparent clip of the actress promoting her underwear line in an interview.
When the interview quits filming, Vergara gets up and starts talking in a British accent.
"Bloody hell, my feet are killing me," she says, storming off in the mock clip. "Where's that chocolate cake?"
