Has Simon Cowell been having an affair with his married baby-mama-to-be, Lauren Silverman, since 2009? That's the allegation of a new Us report.
Though her pregnancy blindsided Cowell, and Lauren and Andrew Sullivan were estranged, a source claims the two have been getting it on for years.
"Lauren has loved Simon forever," says a source close to the NYC socialite, mom to 7-year-old son Adam. "And they started having an affair four years ago."
It began as a fling, but the baby changed that. Simon may or may not be a home-wrecker, as Andrew Sullivan claims he is, but he's committed now.
"Simon and Lauren are together," says a Silverman family source.
