Couldn't he make the same offer to keep Liam quiet

There's just so much that's disturbing about Meg Matthew's account of the birth of her and Noel Gallagher's kid that we don't know where to begin:

"Noel said that if I didn't scream I'd get diamond earrings, so I didn't make a sound, like a Scientologist, and then out came beautiful Anais."

Is it worse that the bribe was made in the first place, or that it was accepted? What sort of father tells the woman he supposedly loves that she should keep her trap shut during childbirth? What sort of woman goes through childbirth more interested in winning a trip to Ratners than the life that's being started?
