Rumors are continuing to swirl about Lauren Silverman, the woman carrying Simon Cowell's baby, and her soon-to-be ex-husband Andrew. 

Sources are telling "TMZ," that Andrew, who was close friends with the reality TV mogul, was fully aware that an affair was going on between the two - and didn't try to stop it. 

The site is reporting that the couple had a "mutual understanding," and that Andrew is now only pretending to be surprised that his wife became pregnant with his child. 

Lauren's attorney contacted the site, saying that many of the statements in their story are "simply inaccurate," but continued to keep the details of the case under wraps. 

Meanwhile, a source close to Andrew is insisting that he had no idea about any relationship with Cowell.
