NEW YORK ( CNN ) -- Former Alaska governor and Republican vice presidential candidate Sarah Palin will co-host NBC 's `` Today '' show on Tuesday , according to Megan Kopf , a spokeswoman for NBC Universal . `` She 'll reveal a different side of her than you 've seen before , '' the morning show 's website boasted Sunday . Last week ABC announced that former `` Today '' host Katie Couric will fill in for Robin Roberts as co-host of `` Today 's '' rival morning show , `` Good Morning America , '' all week . Couric co-hosted `` Today '' for 15 years before leaving for CBS . The matchup of the two women brings to mind Couric 's infamous 2008 interviews with Palin for CBS News when Palin was the GOP vice presidential candidate . Among the details revealed in the course of those interviews was the fact that candidate Palin could not name a single newspaper or magazine that she regularly read . Palin is now a paid contributor for the Fox News Channel . In addition to rekindling memories of 2008 , the two announcements come at a big moment for the competing morning talk shows . According to Nielsen , `` Today '' has won the ratings war for some time , but recently `` Good Morning America '' has been making a steady comeback , threatening to overtake `` Today '' as the top-watched morning show .
Sarah Palin will co-host 'Today ' on NBC on Tuesday . Katie Couric , meanwhile , will co-host the same show with Matt Lauer and Savannah Guthrie at 9 a.m. ` Good Morning America '' Couric interviewed candidate Palin 2008 in an infamous session .
