The photo showed a picture of the actress with husband Michael Cameron and their daughter Kenzie Lynne, who was born in March 2013. They are all bundled up on a crisp winter day.
She captioned the photo, "#tbt to the place where Michael asked me to marry him, and this past year where we stood as a family of three! Can't believe in 2015 we will be a family of 4!!!"
The couple was married in 2008 and welcomed Kenzie five years later. Motherhood has been a joyous milestone in Mitchell's life.
She told Us Weekly in March, "It's changed me in the best and craziest ways. It's slowed me down to enjoy every moment. To really take a look at what's important in life, who's important, and value the time I spend with people."
Mitchell added, "I want to do things that she can watch and I can be proud of. The best and most important role in my life is being a mom."
Her daughter Kenzie is also a big fan of Justin Timberlake, who happens to be married to Mitchell's old costar Jessica Biel.
"She love to dance," she said. "She's got some boogie moves… I think his new record has great rhythms and beats — and it's eclectic — so she loves it. We just turn on Justin and watch her do a little boogie."
The actress definitely wants at least one more kid. As she told the entertainment magazine, "Two or three… No more than three. When you're getting into four, it's a handful. We're not having a 7th Heaven situation!"
Congratulations, Beverley and Michael!
