Actor and model Jonathan Rhys Meyers is going to be a dad.

It will be the first child for the Golden Globe winner and his fiancée, Mara Lane.

Mara announced the news Sunday, Dec. 11 on her Instagram while standing next to Santa Claus, both of them with their respective bellies out.

"#IncomingPackage best present. #ThankYouLord 🙏🙌😇 #SantaBelly 🙊😂," she captioned the photo.

As if that wasn't enough, she later shared a few more images, both of which show her quite far along in the pregnancy. In one image of her in a hammock, she donned a floral dress, while smiling for the camera.

"My official pregnancy dress. I have worn this 1-2x a week every week for past 5 months. It was 3 euros in a charity shop in Ireland 🙊😂," she said. "I love #recycled clothes. #Recycledclothes #antislavery #recycledclothing over fast fashion any day for me 😇 T on the other hand ... #megaprincess owns collars and leashes more than I am."

She then shared an image of her in a purple dress next to a Christmas tree. Again, she showed that her pregnancy was very far along.

"Our other official prego wego dress. Found in #Amsterdam #Noordermarkt for 15 euros 🙋 yes pleasem" she said. "Every other day I dunno as I have other dresses but Baby likes these ones ... is super conscious, connected & aware. Has not let me eat much meat entire pregnancy either ... has me thinking about things I'd rather live in ignorance to. #speciesism waat just stap 😩🙈 😇👽 angel alien baby about to rock my world I already know #thankful for my soon to be best teacher and friend 😍😐."

Jonathan, who starred in "The Tudors" and "Mission Impossible III," hasn't publicly commented on the pregnancy. For now, his lady is doing all the gushing. She even shared a black and white photo of them from months ago.

"I was 6 months and barely showing but thought I was m-a-s-s-i-v-e," she said of the photo, later calling Jonathan her "man crush everyday."

It's not known when her due date is.
