has put to rest speculation that she and Brad Pitt
married in secret – rumors sparked after she wore a simple gold band instead of her diamond engagement ring on a visit to Africa this week.
"Is that a wedding ring, Angelina?" a reporter asks in a video posted to TMZ.com
. "No, it's not," she replies.
Jolie, 37, spent four days meeting with girls and women in eastern Congo on a humanitarian trip to bring attention to the rampant problem of rape there. She returned to Los Angeles on Wednesday.
Pitt, 49, said in November that he and Jolie – his partner of seven years, with whom he is raising six children – would be getting married "soon."
But they have not revealed a wedding date.
