Beyonce Knowles has tried to persuade her sister Solange not to enter into the showbiz in order to protect her. The superstar warned her 22-year-old sister from the high pressure in the music industry. She told InStyle magazine, "I didn't want her to go into the entertainment business. This industry involves a lot of pressure." But Solange followed a solo career anyway. Beyonce also said, ”I am so lucky to have her. We talk on the phone all night. I've been at all of her video shoots, even the ones that take 28 hours.
