This couple has unfortunately encountered several health implications, including a miscarriage via surrogate back in 2011, however, in an interview with People earlier this year, the couple opened up about how they stay strong in troubling times.

"In general, we are pretty tough people. I feel very lucky and fortunate to have the wonderful life I have. We are good at putting things in perspective because of our life experiences. I am not a person to give up when something is important. We feel so lucky to be parents," Arnold explained.

Not only does Arnold have the support of her loving husband and family, but from many fans as well. Fans have been extending their love and support for the star on Twitter using the hashtag #getwelljen.

We send Jen our best wishes!
