The 'Mad Men' Finale And Willow Smith's New Vid In Today's Tweet Dreams

Elizabeth BanksIf you watched last night's surprising "Mad Men" season four finale, you may have had the same reaction as Busy Philipps who posted, "Ugh! Don Draper WTF????????" Actress Elizabeth Banks (pictured) felt flabbergasted, too, as she tweeted, " Season finale of #MadMen had one really big REALLY?!? moment." But, Aubrey O'Day was one fan who loved every unexpected moment of it, as she wrote, "Mad Men touches my heart. The finale was amazing!"

On the other end of the entertainment spectrum, there's some major buzz surrounding Will Smith and Jada Pinkett Smith's daughter (not to mention Jaden Smith's sibling) Willow Smith. The pint sized up-and-coming pop star alerted followers, "Whip My Hair the video premieres today on @106andpark and @vevo check out the exclusive teaser clip" But, it seems the vid already gained some famous fans, including Missy Elliott, who wrote, "Willow Smith!!!! #ExcitingYoungArtist!!" Even Justin Bieber gave a shout-out to Willow when he tweeted, "heard my lil sis Willow Smith video is coming out tonight. its CRAZY!! keep a look out for it."
