• Did John Edwards propose to Rielle Hunter the same day he finally fessed up to being the father of Hunter's 2-year-old baby?

• John Mayer made a bunch of stupid comments in an interview with Playboy earlier this week. And he's been apologizing for them ever since. [Us, P6]
• A new season of Real Housewives of New York City returns in a couple of weeks and Kelly Bensimon is doing her damndest to remain front and center.
