Adrienne Bailon is a NEW MOM, and Khloe Kardashian is over the moon happy.

Bailon used to date Rob Kardashian in the early 2000s when the famous family was rising to fame.

In fact, Bailon was more famous than Rob and his family when they dated from 2007 to 2009.

“The Real” co-host announced she welcomed a baby boy on Instagram on Tuesday, August 16.

Khloe was among the top verified followers to comment on the post.

“I am so beyond happy for you A!!! He is the luckiest little boy to have you both as his parents. You are going to be the most incredible mommy! I love you! Enjoy every second ❤️,” she wrote.

Khloe just welcomed her first son via surrogate as well.

While Adrienne has debuted her little love to the world, Khloe on the other hand has remained mum about her newborn son.

All we know is that the baby has been born and was carried by a surrogate.
