She's so cute!

Serena Williams welcomed a little girl with fiance Alex Ohanian almost two weeks ago, and now she's showing her off on Instagram! Daughter Alexis Olympia Ohanian Jr. made her debut on social media this morning, and she looks a lot like her tennis legend mama.

"So we’re leaving the hospital after six, seven days. It’s been a long time, but we had a lot of complications, but look who we got — we got a baby girl!” she said in an accompanying clip.

The athlete also shared a video montage of the couple's most private moments leading up the birth, from ultrasounds to assembling the crib in their nursery, and it's pretty obvious they're head over heels for each other.

The pair decided to wait to find out the gender of their first child, but both had a hunch pink was in their future.

“[Serena] won the Australian Open while pregnant. And she remarked that she feels like it has to be a girl because everything that that baby went through and handled like a champ, only a woman could be strong enough to take on," Ohanian said on a late night appearance.

Congrats to the happy parents!
