There's a common misconception that being knighted is the only way for a woman to be recognized for her achievements in the UK. While knighthoods are the most famous form of honor, women can also receive the honor of being made a Dame Commander of the Order of the British Empire (DBE). This is equivalent to a knighthood, and Billie Piper has not received this honor either.
It's important to note that being knighted or receiving a DBE is a significant honor bestowed for exceptional contributions to society. It's not something that is given lightly.
