Kelly Rowland's son Titan is only two days old and he's already got some pretty impressive friends.

Beyoncé took to Instagram on Thursday to share congratulate her BFF on becoming a mom for the first time. And the "XO" superstar also shared the first photo of Rowland's baby boy.

"There's no better feeling than holding my beautiful nephew," wrote Beyoncé on Instagram. "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."

How sweet?

In the photo, Beyoncé can be seen holding Titan's hand. No doubt, little Ty can already count Bey and Jay-Z's daughter Blue Ivy as one of his closest friends.

Rowland and her husband Tim Weatherspoon welcomed their first child, Titan Jewell Weatherspoon on Tuesday, Nov. 4 at 1:30 p.m. PT. The newborn weighed 7.5 lbs.

"We are thrilled to announce that today we are the proud parents of our first son," the "You Changed" singer told PEOPLE in a statement. "We are blessed to report everyone is healthy and happy!"

Beyoncé also posted an Instagram photo of Rowland on Thursday, one taken from a photoshoot with Elle in which the then-pregnant singer put her baby bump on display.

In fact, Rowland even stripped down to show off her bare stomach in several of the stunning photos. In the Elle interview, she explained that she felt the need to rejoice the strength and beauty of a woman's body.

"I took a birthing class and I was amazed by all the things this woman was saying to me about birthing and what the body does naturally," Rowland told the magazine. "Why wouldn't you want to celebrate that?"
