Kim, Kanye and the fetus were all smiles (well, maybe not the fetus ... it probably looked kinda smushy) ... and who wouldn't be.  Kim raked in 6 figures for the appearance at the club inside the Mirage.

John Legend, his fiance Chrissy Teigen and Lance Bass joined the party. 

Kim is approximately 3 months pregnant.  Even with morning sickness, it would be hard to pass up this kind of payday.

Do ya think this whole thing was timed?
