Well that was quick!

Serena Williams gave birth less than a month ago, but she's already got her post-baby bod back! The tennis champ slipped into a sexy body con dress for date night at the Bruno Mars concert with fiance Alexis Ohanian last night, and we can't believe how good she looked!

The athlete is relishing in new motherhood, and she recently penned a letter to her own mom to thank her for teaching her the hard lessons in life.

"Dear Mom, you are one of the strongest women I know. I was looking at my daughter (OMG, yes, I have a daughter 😳) and she has my arms and legs! My exact same strong, muscular, powerful, sensational arms and body. I don't know how I would react if she has to go through what I've gone through since I was a 15 year old and even to this day," she began.

"I've been called man because I appeared outwardly strong. It has been said that that I use drugs (No, I have always had far too much integrity to behave dishonestly in order to gain an advantage). It has been said I don't belong in Women's sports -- that I belong in Men's -- because I look stronger than many other women do. (No, I just work hard and I was born with this badass body and proud of it). But mom, I'm not sure how you did not go off on every single reporter, person, announcer and quite frankly, hater, who was too ignorant to understand the power of a black woman," she continued.

"I am proud we were able to show them what some women look like. We don't all look the same. We are curvy, strong, muscular, tall, small, just to name a few, and all the same: we are women and proud! You are so classy, I only wish I could take your lead. I am trying, though, and God is not done with me yet. I have a LONG way to go, but thank you. Thank you for being the role model I needed to endure all the hardships that I now regard as a challenges--ones that I enjoy. I hope to teach my baby Alexis Olympia the same, and have the same fortitude you have had," she gushed.

We can't wait for her wedding!

Ladies is a "push present" a thing? If so what did you get if anything? #conversationstarter
