Beyonce and Mum Left Blushing

Beyonce and her mum, Tina Knowles, launched their clothing range 'House Of Dereon' in Chicago last week but were left red-faced after being told theyd got their sizing all wrong.

The Knowles ladies were at a filmed press conference when one journalist told them various stores in the city had had to send their HOD clothes back, complaining of a poor fit.

According to our colleagues at MTV.com, Beyonce was left looking highly uncomfortable, while her mum went on the offensive.

"Why would you do that? You're here to interview us about the clothes, in a positive light. I dont want to talk about that on air," raged Knowles Senior before demanding that the cameras stop rolling.

Unfortunately for Bey and her mum the embarrassing few minutes of film has got out and is now doing the rounds on the internet
