"I think he's super excited because he's not going to be the youngest anymore. He's always kissing my belly," Keys told PEOPLE in October.

Keys announced her pregnancy in July this year, also via Instagram. She posted a photo of herself and Swizz Beatz posing for a picture captioning it:

"Happy Anniversary to the love of my life @therealswizzz!!"
