The actress, 36, is pregnant, expecting her second baby, a boy, with husband, Tanner Novlan. The pair is due to welcome their son in August.
Ewell tells PEOPLE she was "already a month and a half pregnant" when she found out about her pregnancy around Thanksgiving.
The Vampire Diaries star and Novlan are already parents to two-year-old daughter Poppy. The couple feels "lucky" to have both a son and a daughter.
"I really wanted to be a boy mom. I'm excited to meet him. It'll be fun," she says.
As for Poppy, Ewell says she can't wait to be a big sister and lets everyone know about it.
"She tells everyone on the street, even dogs on the street, that she's a big sister, and she's really excited about it," adds Ewell.
The soon-to-be mom of two also expresses her excitement to be able to raise her son in a "somewhat 'normal' way," as Poppy was only "six months when the pandemic hit."
"We have a little bit more of a semblance of what life will be like," Ewell says. "So, in a way, even though it's our second baby, it'll be our first time experiencing it in a somewhat 'normal' way. As normal as we are right now, which is not normal."
The pair dated for five years before they decided to go for it and get married. But on September 12, 2015, they made it official with 200 of their closest family and friends in attendance.
