Whoever said the reality-TV craze was over obviously hasn't talked to the suits at NBC. This summer, the Peacock will be feathering its nest with three returning reality shows and yet another new one. First up is America's Got Talent, which kicks off on May 29 with incoming ringleader Jerry Springer (sans bodyguards... I assume). Next, the fifth cycle of Last Comic Standing premieres June 13, with Bill Bellamy as host. Frosh date-a-thon Age of Love, fronted by Mark Consuelos (aka Mr. Kelly Ripa), bows June 18. And last but not least, The Biggest Loser hits the treadmills in late summer, with Days of our Lives' minx Alison Sweeney presiding over the weighting game.
