Taking to Instagram last night, Testoni announced the exciting news in her ever-stylish way, revealing she and her husband, Leith, are expecting a boy.
"Well, 2018 is going to be WILD," the 29-year-old wrote.
"We will be welcoming a little boy to our family 💙 #SURPRISE."
The couple, who both work in the fashion industry, wed in 2014.
Congratulations! We can't wait to see the new addition.
