Super sexy Beyoncé and mom Tina Knowles are super close, but are the two so close that they share the same diet?!
Miss B tells "Extra" she says to her mom, "Eat whatever I eat and you're going to be good."
The diet tips aren't mean-spirited -- Tina tells "Extra" the slim-down was her idea. She says she first asked her daughter for the help, but she sometimes regrets it!
