The songstress posted a birthday card on her Tumblr page that said, "Happy Birthday Miss Carter…Happy 2nd birthday Blue!"
Baby Blue was spotted leaving lunch in the arms of her papa while Queen Bey flaunted her killer abs in a pair of high-waisted jean shorts and a white crop top.
The birthday girl was equally as fashionable and seen wearing head-to-toe gold with a pair of brown gladiator sandals.
"I wanted to show that you can have a child and you can work hard and you can get your body back. I know finding my sensuality, getting back into my body, being proud of growing up, it was important to me that I expressed that in my music because there are so many women that feel the same thing after they give birth."
The Grammy winner added that she wanted to serve as an inspiration to new mothers everywhere.
