However, the announcement also revealed she had suffered a "devastating" loss in 2020.She later confessed that she "had a hard time being excited" during the early months of her pregnancy.
"I had a hard time feeling really excited for the pregnancy because I was nervous something may go wrong and this baby wouldn't make it," she told fans.
"Going through a loss like that is difficult but in a lot of ways it caused me to be more way more grateful and realise what a blessing it is to have a healthy pregnancy and carry a baby to term and not have complications," she concluded.
