"There's no better feeling than holding my beautiful nephew," Bey wrote. "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."
In addition to her sweet message, the "Love on Top" singer shared a precious pic of little Titan's hand holding on to a pair of adult hands. Too cute!
Beyoncé shared a second photo of Rowland posing during a pregnancy photo shoot. In the glamour shot, Rowland strikes a beautiful pose while holding onto her baby bump.
Rowland welcomed Titan on Tuesday, Nov. 4. The newborn arrived at 1:30 p.m. and weighed in at 7.5 pounds.
Just yesterday, Bey and Kelly's Destiny's Child bandmate Michelle Williams gushed over the birth. "She's doing very well," Williams told E! News. "Kelly's going to be an amazing mom. She's always been great with children. She loves babysitting, she loves buying stuff for kids. She has such a big heart. She's a giver and a nurturing person and, really, that's what motherhood is all about."
