In a Sept. 21 Instagram post, Lee, an actress as well as avid equestrian, announced the news of her pregnancy, writing “New life in the new year ✨”.

Two months later, in November, Welling shared a sweet polaroid of himself with Lee’s pregnant belly, captioning the image with the hashtags “#thankful #thankful #thankful #baby.”

The couple confirmed their engagement in early 2018 when they both referred to each other as “fiancé” on Instagram.

In February, Lee posted a sweet tribute to Welling, 41, writing, “To my perfect fiancé- I love you to infinity and beyond. Thank you for all of your unwavering support and super-human love. I am so blessed to have you in my life ♥️. @tomwelling.”

In April, Welling followed with his own Instagram, using the hashtag “#fiancé.”

“Love : from half way around the world #love @jessiroselee#hereslookimgatyou #letsgo #babe#barcelona #goldcoast #aka #sea #beautiful#fashion #happy#smile #fiance #saddleclub,” he wrote.

Though it’s unclear how long they’ve been together, Lee has been posting photos of the couple since as early as 2015.
