The pair, who tied the knot in 2014, revealed they were expecting a rainbow baby two weeks ago — and despite being just 10 weeks pregnant, Jamie was not deterred from announcing the pregnancy publicly.

"The moment I found out I was pregnant I began telling everyone," she captioned a photo of her belly painted with a rainbow. "I wanted to share with family and friends before announcing publicly, but I knew I wasn't waiting the socially acceptable "3 months" like I was "supposed" to."

She continued, "I feel like it should be each woman's choice whether they want to keep their pregnancy private or shout it from the rooftops! Who made the rule for women to have to wait 'just in case?' I know I'm not the first to announce my pregnancy early and I hope I'm not the last."
