Collins, who told Couric he's never been attracted to young boys, instead described himself as someone with "exhibitionist urges" and "big boundary issues." The actor has admitted that his "urges" got the better of him in 1973 when he says, in his People magazine statement, that he "moved [an underage girl's] hand in such a way that caused her to touch me inappropriately."
He told Couric that his actions were "terrible" and that he "regrets them deeply."
Collins was also adamant that this was the only time he has inappropriately touched a minor, though he did admit that he exposed himself to a teenage girl in 1982 and another in 1994.
His conversation with Couric is Collins' first sit-down interview since TMZleaked a 2012 recording this past October. The voice, purportedly Collins, speaks on his inappropriate contact with minors during a therapy session with his estranged wife Faye Collins.
Collins is now in the midst of divorce proceedings with his wife and is being investigated by authorities in both Los Angeles and New York. He has not been charged, and claims he has been in treatment for 20 years.
Couric's full interview with the 67-year-old actor will air tonight, Dec. 19, on ABC's 20/20.
