-- Welcome to the limelight, Sir Carter and Rumi!
In the photo, Beyonce -- wearing what appears to be a light blue veil, reportedly at her oceanside Malibu home against a backdrop of an arch composed of colorful flowers -- is holding the newborns, who are partially draped in floral fabric.
The singer's mother, Tina Knowles, also confirmed that the newborns are in fact a boy and a girl.
When reposting the photo Beyonce used to reveal the newborns, she captioned the Instagram photo: "So Happy my baby shared a photo of her babies with the world proud grandma hello Sir Carter and Rumi Carter Boy and girl what a blessing."
Beyonce, 35, announced in a February 1 Instagram post that she and husband Jay Z, 47, were expecting.
"We would like to share our love and happiness," read the post, alongside a photo of the singer wearing a veil, with her hands on her bare belly. "We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. - The Carters."
Sir Carter and Rumi join the couple's 5-year-old daughter, Blue Ivy.
