Now that we know what was really going on, these pictures make a lot more sense!

Simon Cowell is expecting a baby with his former best friend's wife Lauren Silverman, so now we understand why we caught them being super affectionate on a yacht in St. Barths in January 2012! That still doesn't explain why the pair were getting cosy under her husband Andrew's nose... literally!

The group was vacationing together in the Caribbean aboard the X Factor judge's boat, and even though the brunette beauty was caressing the British lothario's hair and stealing smooches with him, her hubby didn't seem to mind!

Well, that's all changed now that news broke the 36-year-old is expecting her first child with the music mogul!

Andrew Silverman filed divorce papers two weeks ago in New York, and the real estate broker cited adultery as the cause of the split and Mr. Cowell as a co-respondent!
