Serena Williams hit back at her critics in an emotional letter to her mother.

In the letter, which Williams shared Tuesday on Reddit, the 23-time Grand Slam champion thanked her mom, Oracene Price, for giving her the strength to endure the challenges she's faced and said she hopes to pass on the same lessons to her own daughter, Alexis Olympia Ohanian Jr.

She also described the physical similarities she shares with daughter, proudly stating, "she has my arms and legs!"
