We wanted my Yiayia to pop the ballon in front of 50 of our family members. We wanted to make it special for them and make it their best Christmas ever so we waited for a couple more days to reveal to Yiayia and Papou what we are having! From the first day we found out we were pregnant Tobi said “It’s a girl!! I can FEEL IT!!… but for now, I will call her baby muffin… but I know it’s a girl, I love her so much already, when can I meet her? How long do I have to wait? This isn’t fair!!! I want to hold her now” haha sooooo cute!! ???????? Happy New Year everyone!!! Xxx Kayla and Tobi xxX ????????

The second video shows the couple popping a balloon in a more intimate setting with Itsines’ grandparents.

Last week, Itsines and Pearce announced they’re expecting their first child in May, 2019.

“Tobi and I do not even have words to describe how happy and excited we are to bring you this news! If you don’t know already, I come from a big greek family. FAMILY is always what comes first in my life. To be able to start my own family with the person I love most in this world is just an absolute dream come true,” she wrote.

“@tobi_pearce has been SO supportive, SO EXCITED and so loving! He comes home every day, hugs and kisses my stomach. He lays on my legs and asks the baby how it’s day was. He is at every scan and every appointment. I couldn’t ask for a better partner. Our family, well haha.. you can just imagine – they are of course ABSOLUTELY OVER THE MOON EXCITED. I know you are already picturing the look on their faces when we told them,” she added.
