Just days after telling ET
that she is expecting a second child with husband Dakota Meyer, Bristol Palin announced that only Meyer knows the sex of their upcoming bundle of joy.
In a new update on her blog
, the 26-year-old mother of two expressed her excitement for their new addition, along with their "unconventional" news about the baby's gender.
"Keeping with our unconventional life, it has been so much fun to keep this news just among our family and friends for the first half of our pregnancy; that Dakota knows the baby’s gender but the rest of us won’t until he or she is born," wrote the Dancing With the Stars alum.
Palin, who shares 7-year-old son Tripp with ex Levi Johnston, added that she always knew she would have another child with Meyer, after having daughter Sailor a year ago.
"Even while pregnant with Sailor (under more unconventional circumstances), I always knew a third child someday would complete our family," she added. "We are all overjoyed!"
The couple wed seven months ago in a surprise ceremony, after calling off their previous engagement in the spring of 2015.
