“We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. – The Carters,” Beyoncé wrote, revealing her baby bump on Instagram.

The happy news spread quickly on social media, where many users expressed surprise, joy and congratulations.

The couple welcomed their first child, Blue Ivy, in 2012.

There was no word on the gender, but Beyonce has always been private about her family life. Many remember how she revealed Blue Ivy was on the way at the Video Music Awards in 2011.

“I actually didn’t announce it, I didn’t want to put it in a statement. I thought it’s better to just show everyone,” she said.
