Forbes magazine just named Oprah Winfrey the the "Most Influential Celebrity in America" for the second year in a row. Editors said Oprah's headline-grabbing interview with Lance Armstrong helped her land the number-one spot on the list. The cyclist confessed to years of illegal doping during the candid chat.

Meanwhile, the media mogul opened up to talk show host Steve Harvey about her sex scene with Terrence Howard in the upcoming film "The Butler."

"It was supposed to be like a little scene, and because Terrence Howard misbehaved it turned into a bigger scene, and then a bigger scene," she explained.

Howard recently talked about working with Oprah and her "tig ol' bitties." He also called her a "lovely, voluptuous woman" and "very, very beautiful."

In response to his remarks, Oprah explained: "Some people called me and said they were all offended, but I do have big breastses." At this - Steve Harvey gave her a high five.

"The Butler" centers on a White House butler who served eight American Presidents over the course of three decades. It opens in theaters in October. The film also stars John Cusack, Robin Williams and James Marsden.
