The actress announced the good news on her Instagram this Sunday, December 5, 2021.
Dionne revealed her pregnancy during her birthday, saying that this news had made this birthday the "best... so far."
She also acknowledged how the year 2021 had been giving her "sooo much!"
Her Instagram caption read: "I moved to a new country, learned a new language, discovered new interests, got engaged, married my best friend & love of my life @nayr_redlats, and together, we traveled & discovered different countries & cultures."
But for Dionne, her pregnancy marked the beginning of their "most exciting adventure yet!"
The soon-to-be mother gushed about this new sensation, saying she has never been "this in love with life, and with love itself. I am so wildly grateful to the universe for conspiring in my favor."
Dionne started this year by revealing her engagement in February 2021.
A month after announcing her engagement, she and Filipino-Swiss husband Ryan Stadler tied the knot.
Since then, Dionne had been sharing glimpses of her new life in Switzerland on Instagram.
