Fanning, just tell her that you were judging the crap out of Wally's Baby momma because she doesn't hold with good traditional values. Feel free to freeflow some bullshit here, but I would tell her that Wally immediately tried to marry her when he found out that he was having a kid and that she then immediately started rebelling against the idea of traditional family values and decided to sleep around with other athletes.
Just tell her that your tweet was your way of speaking against the decay of the family in our society.
