It seems Blue Ivy has also taken to her new role as big sister.
As for JAY-Z's revealing new album, "4:44", Tina said she wasn't surprised at how candid the rapper was on the record because "it's art" - though she wouldn't say whether Beyonce was working on another album after giving birth to the twins.
Besides it being their first public photo, Beyoncé's post was also the first time the names of her twins were officially confirmed. The latest picture was reminiscent of her pregnancy announcement (also on Instagram) that was inspired by Yoruba goddess Oshun.
Tina gushed about the cute twins, saying that they are all excited to have them in their lives and see them grow up.More news: HBO Unveils First Look of Al Pacino as Joe Paterno
Lawson's husband, Richard Lawson, echoed her sentiment.
Tina's caption reads, "So Happy my baby shared a photo of her babies with the world proud grandma hello Sir Carter and Rumi Carter 7/13/2017 Boy and girl what a blessing". She's a good big sister and cares for them a lot', said Tina Knowles in an interview with Entertainment Tonight.
Of course she is! You can find her over on Instagram constantly supporting and loving on her daughters and their friends.
Mom Tina Knowles Lawson kicked off the family praise, reposting the photo on Instagram.
Congratulations to the now even larger Knowles-Carter fam.
