Kelly Rowland is a mother now. The former Destiny's Child singer welcomed her first child Titan Jewell Witherspoon, on Tuesday, and she's not the only one who's thrilled about the new addition to her family. So is Beyoncé

Bey hit Instagram to share a sweet note about her new "nephew." It was accompanied by a photo of a mom and baby's tiny hand clasping each other, and she followed that with another photo of a pregnant Rowland, captioned, "G."

"There's no better feeling than holding my beautiful nephew," Bey's full post reads. "I thank god for the honor of witnessing my sisters journey into motherhood. I've always dreamt of our little ones growing up together. I'm so thankful for our bond. Baby Ty, I love you so much. Congrats to my Spoons."
