Pop superstar Madonna is considering having plastic surgery to retain her youthful looks, but insists she won't tell fans about her cosmetic help. The HUNG UP singer, 47, maintains her famous figure with a rigorous fitness routine, but admits she may need extra help to keep wrinkles at bay. She says, "I am not going to hold a press conference if I have plastic surgery. "But I have said many times, I think about it, like everybody, and I sure don't rule it out."
