Welcome to the Smart Set. Every morning we bring you the gossip coverage, filtered. Today: Keith Olbermann and Current TV can't agree on why he wasn't on the air last night, Maria Shriver and Arnold Schwarzenegger are wearing rings in public again, and Al Roker is not the person to ask for a favor on a long flight.

Maria Shriver and Arnold Schwarzenegger have both been photographed out and about in recent days with rings on their wedding fingers. That's strange, because Shriver filed for divorce back in July. According to a TMZ source, Shriver  has been telling friends she's not sure she can go really go through with the split, because she's Roman Catholic. The source adds that Arnold has been an "incredibly sweet" effort to win Shriver back, mainly by showering her with unspecified gifts.    [TMZ]

Keith Olbermann's absence from Current TV's coverage of the Iowa caucuses won't do much to dispel the chatter that the anchor is once again feuding with his network overlords. Olbermann stiffly tweeted that Current informed him he wouldn't be on the air, which a network spokesman contradicted in a chat room on the network's Web site, insisting that Olbermann turned down the chance to anchor on his own.

Jonah Hill and Dustin Hoffman's daughter Ali are dating. Good for Jonah Hill and Dustin Hoffman's daughter! A source says Hill spent time in Hawaii over the holidays with the family, which would be a stressful and claustrophobic situation even without Dustin Hoffman in the mix. Somehow, Hill made it back to mainland with his sanity and relationship intact.  [Page Six]

Al Roker's airplane etiquette is apparently less-than-stellar. A spy accuses the Today Show weather man of "nearly pulling an Alec Baldwin" on a flight to New York on Monday, because he kept talking on his cell phone after the plane left the gate. Also, he wouldn't swap seats with musician Alex Van Halen, who wanted to sit next to his wife during the flight, and was even willing to take the middle seat to do it. Roker refused, Van Halen "bitterly complained to the gate agent" about the breach in protocol, but didn't get any results. [Page Six]

Celebrity stylist Rachel Zoe was "suspiciously covered up" during a walk on the beach in St. Bart's. According to Radar, that can only mean one thing: Zoe is pregnant and trying to hide it from the world. Just like Kate Middleton! [Radar]
