NEW YORK (AP) ? Taking a full year to name a replacement for Michael Strahan beside Kelly Ripa on the morning chat show "Live" paid off in a big way for producers, who roped in Ryan Seacrest as co-host. The former "American Idol" host debuted Monday on show, giving Ripa a marquee name to banter with at when she is about to go head-to head with Megyn Kelly on NBC's "Today" show. The stretch of guest co-hosts dragged on so long that there were rumors Ripa was more interested in going it alone than in finding a regular to join her.
