Chris Cuomo joins Elizabeth Vargas as co-anchor of "20/20" with back-to-back hour reports airing Friday, December 18 (9:00-10:00 and 10:00-11:00 p.m., ET) on the ABC Television Network:

9:00-10:00 p.m. - Anand Jon was once a rising star in the fashion world, named a hot new designer by Newsweek magazine, and he was even featured on the hit television show "America's Next Top Model."  But this man famous for dressing women in style was accused of undressing young girls and taking advantage of them behind closed doors. Was he a sexual predator as accused by the teenage victims or, as he and his supporters claimed, a victim himself of a sinister plot by disgruntled models fueled by jealousy and greed? Jim Avila reports on the case, trial and a bizarre courtroom twist that could set Anand Jon free, regardless of the jury's decision.

10:00-11:00 p.m. - Chris Cuomo reports on two American children stuck in two Italian orphanages and their two fathers on a mission to get them back. For most Americans, a trip to Italy would mean a romantic getaway or a vacation to take in the sights. But not for 48-year-old Michael McCarty, who has made more than 15 trips to Italy over the past two years, desperately trying to bring his eight-year-old son, Liam, back to the United States. His ex-wife, Manuela Antonelli, abducted Liam and took him to her native country more than two years ago. He has been at the center of an international custody dispute ever since. And 28-year-old Brandon Henry is trying to unite with his son whom he has never met. His pregnant fiance fled to Italy with their yet-to-be born boy and abandoned him in a convent shortly after his birth. The Italian government has kept father and son apart for over a month, raising and dashing Brandon's hopes repeatedly. Cuomo has been following both cases for more than half a year.

"20/20" is anchored by Elizabeth Vargas and Chris Cuomo. David Sloan is executive producer.
