Used to sweating it out with Kayla Itsines after a few days a week [1]? Well according to the trainer's Instagram, you may be getting a new workout buddy [2] because she's officially expecting a baby with her long-time partner Tobi Pearce. She shared the news in a sweet video on Dec. 18 [3], and we can't get enough of it.

"20 WEEKS PREGNANT," she wrote in the caption. "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. Tobi 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."

Congrats to their growing family!
