More Real Housewives

Bravo has renewed the New Jersey and New York versions of its Real Housewives franchise for another season each. The news comes right after nearly 4 million people tuned into part 1 of the Real Housewives of New Jersey reunion, the network's highest ratings of the season. You can also check out the cast for the sixth version of the franchise, The Real Housewives of Beverly Hills. [The Hollywood Reporter]

Fewer Real Housewives

While The Real Housewives of New York City will be back, Bethenny Frankel won't be. After getting her own spin-off, Bethenny told Us Magazine that she won't return for the fourth season. [usmagazine.com]

America's Got Even More Talent

NBC has renewed its summer hit, America's Got Talent, for a sixth season. So if you are marginally talented, or just an entertaining trainwreck, you too can win your own Vegas show.

Wedding Bells on Grey's Anatomy
