Oprah has interviewed everyone from Michael Jackson to President Obama, but there’s one celebrity who has evaded her. According to the media mogul, Lauryn Hill turned down an offer to sit down with her.

Following her revealing interview with Rihanna for “Oprah’s Next Chapter,” one of O’s Twitter followers asked her to get Lauryn Hill on her show, but the elusive superstar was not interested. “Tried. She said no,” tweeted Oprah.

Winfrey has scored exclusive interviews with Whitney Houston’s daughter Bobbi Kristina, 50 Cent, the Kardashians, and Paris Jackson for the latest season of her OWN program.

Another star who’s not quite ready to have a heart-to-heart with Oprah is Beyoncé. While the private singer appeared on her daytime talk show several times, she has been reluctant to say yes to an in-depth interview. “See if you can convince Beyonce, I haven’t had luck yet,” Oprah told one fan.

The embattled Fugees frontwoman is facing three years behind bars after intentionally failing to file tax returns in 2005, 2006, and 2007. She will be sentenced in November.
