No, they are not her real children. They are actors to represent
a "daughter" and her friends. Kelly has two sons and a daughter,
not three girls as represented in the commercial.
She signed a contract in 2004 that was a 5 year deal, which
means it ended in 2009. That contract included the following..
"Reege's co-host to bank at least $27.5 million, though her haul
could top $40 million thanks to a revenue sharing clause in the
syndication contract. She also gets a maximum $75,000 clothing
allowance and can look forward to eight weeks vacation in the
deal's final four years (she'll have to make do with six weeks off
during the deal's first year). And if she feels like procreating,
Ripa is entitled to six weeks maternity leave during each year of
the deal
