NEW YORK — Bono is afraid of Alicia Keys.

While Keys talked about being pregnant and empathic when filming her documentary about AIDS in Africa, the U2 singer chimed in and said: “She’s scary, isn’t she? She’s scary.”

Bono went on to say that Keys has “lioness energy” and that her role as a new mother won’t allow her to “let other mothers suffer.”

He made the comments at the premiere of “Keep a Child Alive with Alicia Keys,” a documentary which followed a visit to South Africa during last year’s World Cup with a pregnant Keys and five Americans. It airs on Showtime on Dec. 1, which is World AIDS Day.
