Tina Knowles hopes Blue Ivy Carter "doesn't go into entertainment"

She told Extra: "My wish for her is that I wish that she would do something else. I hope that she doesn't go into entertainment.

"I think it's a huge sacrifice. It's a huge sacrifice on your life. But if she chooses to do it, I'm going be right up front screaming and cheering.

"But hopefully she'll choose something else, but what I do know? And that's why her mom let her do it, is because she got her confidence there. And it's beautiful to see."

Tina pointed out that Blue's seven-year-old sister Rumi - who Beyonce also has with husband Jay-Z -has also loved getting to join her mother and sibling on stage during the recent run.

She added: "Little Rumi also, she told us every night during Renaissance, 'I'm ready. I'm ready to go out there,' and we were like, 'Okay, next time.'

"And this time, her mom let her go and it's wonderful to see her out there.

"They need to let her let loose 'cause she is back there doing choreography and twirling and doing all pliés and everything else. And I'm like, 'Let her loose one night!' "

Despite her reservations about Blue or Rumi chasing a career in music, Tina is delighted to see Blue gaining confidence by the day.

She said: "Well, it's the best, because at the end of the day, the most important bonus of that is I just see the confidence just growing every day.

"Blue is tall, she's like 5'9", and she's 13 years old... and I would always say, 'Stand tall because your grandma always wanted to be tall.'

"And she would still kind of slump a little bit, and now we got the model pose and she is strutting and she is confident and that's the most important thing to me."
