Seacrest, In at GMA? 'American Idol' Host Has Tuesday 'Today Show' Announcement

It's not as if he isn't everywhere these days anyway, but throwing Ryan Seacrest into this week's star-studded network morning show lineup? Sure, why not?

The "American Idol" host, E! correspondent, syndicated radio host and all-around omnipresent pop culture overseer Ryan Seacrest will join a Tuesday "Today" show broadcast on NBC already co-hosted by former Fox News correspondent, vice presidential candidate and Alaska Gov. Sarah Palin. Seacrest has a major announcement planned that Deadline speculates concerns his in-the-works NBC Universal deal.

Specifically, Deadline believes that Seacrest's announcement will detail a new deal with NBC Universal partner Comcast's E!, where Seacrest has had a red-carpet presence since 2006. It's rumored Seacrest may become a part-time "Today" presence - an interesting development, since there's no telling how much longer current co-host Matt Lauer may keep up his gig - and joining NBC's London Olympics coverage this summer.

NBC entertainment chairman Bob Greenblatt claimed after meeting late last year with Seacrest following Comcast's merger with NBC Universal that there's interest in Seacrest not only producing scripted shows for both E! and NBC, but also leading a line of Barbara Walters-esque prime time interview specials. Those possibilities must be growing all the more lucrative since FOX will probably start negotiating with Seacrest after his "American Idol" contract ends following this season. There's additionally always his radio work with Clear Channel that must be considered.

Surely at some point, something's got to give. It might even be the AXS television network he's launching alongside Dallas Mavericks owner Mark Cuban and AEG.

Elsewhere, "Today" goes head-to-head this week with former hostess - and longtime Palin rival - Katie Couric guest-hosting ABC's "Good Morning America" this week in place of a vacationing Robin Roberts.
