London, January 3: Singer Beyonce Knowles has reportedly left fellow artist Janet Jackson fuming after referring that the latter's family did not come from an upper class background.

The leading R&B lady seemed to have taken a dig on Jackson family by contrasting her wealthy upbringing against that of Janet, who comes from the working class area of Gary, Indiana.

"I grew up upper class. Private school. My dad had a Jaguar," the Daily Express quoted Beyonce as telling Elle magazine in a recent interview.

"We''re African-American and we work together as a family, so people assume we''re like the Jacksons - but I didn''t have parents using me to get out of a bad situation," she added.

And according to the New York Daily News, Janet was said to be so livid with the remark that she was planning a head-on confrontation with Beyonce. (ANI)
