In an exclusive interview, actor Corey Feldman speaks out with surprising new claims about his relationship with Michael Jackson when Feldman was a child star and the two were friends. Feldman, who has stood by Jackson until now, tells why he is now coming forward with allegations about their friendship to ABC News' Martin Bashir. "I started looking at each piece of information... and with that came this sickening realization that there have been many occurrences in my life and in my relationship to Michael that have created a question of doubt." The interview airs on "20/20," FRIDAY, FEBRUARY 11 (10:00-11:00 p.m., ET) on the ABC Television Network (for transcript information, please call 212.456.1624).

Plus: ABC News Chief Investigative correspondent Brian Ross uncovers misconduct, sexual exploitation, and worse by U.N. peacekeeping personnel in the Democratic Republic of Congo, despite repeated public assurances from United Nations officials that significant steps have been taken to address the problem. The ABC News team observed and filmed U.N. peacekeepers leaving a bar with prostitutes loaded into their U.N. vehicles and obtained graphic pornographic footage from the computer hard drive of a senior U.N. official from France of the official having sex with numerous Congolese young women and girls. Ross interviews young Congolese girls who provide moving personal accounts of rape by U.N. soldiers and reports on the estimated hundreds of babies left behind by the U.N. personnel. Aid workers describe desperate people trading food for sex. "We have heard cases where they have traded eggs for sex or a jar of peanut butter for sex," says Anneke Van Woudenberg of Human Rights Watch. This exclusive investigative report clearly demonstrates that the ongoing problems are far from being solved, as even this week the U.N. announced it would be sending additional military police to monitor the behavior of its own troops.

And: If it seems men are slow to say "I do" lately, that's because it's true. Years ago they were tying the knot in their early 20s; now they are waiting until almost 30. ABC News Correspondent Deborah Roberts introduces viewers to Daniel Rosenberg and Richard Kirshenbaum, an unlikely duo who say that are coming to the rescue of all those women left cooling their heels by boyfriends with cold feet. The two, who were once die-hard bachelors and are now happily married, are sharing their secrets in a new book, Closing the Deal: Two Married Guys Take You From Single Miss to Wedded Bliss. "If you were going sky diving, would you rather hear from a physicist or a paratrooper? And you know, we're the paratroopers," says Rosenberg. But does their advice really work? "20/20" follows two couples for a first-hand test.

"20/20" is anchored by Elizabeth Vargas and John Stossel. David Sloan is executive producer.
