The Bachelor's Snezana Markoski and Sam Wood are expecting a baby!

Snezana Markoski is pregnant!

The Bachelor alum appropriately announced her and fiancé Sam Wood's happy news on Instagram on Mother's Day. 

"We're so excited to be able to let the world know that our little family of 3 is soon to become 4," the 36-year-old captioned a photo holding her growing baby bump next to her 10-year-old daughter Eve (from a previous marriage). 

"@samjameswood you are going to make an incredible father ❤ Thank you to @vicky_papas_vergara for capturing this beautiful moment. #HappyMothersDay." 

Sam also shared an adorable Instagram snap pointing at Snezana's belly.

"Snez ........... a) has just eaten a bowl of pasta bigger than her head b) can't do up her pants c) is having a BABY!!! d) all of the above #theanswerisd #happymothersday#soexcited," he captioned the sweet shot.

Snezana and Sam met on season three of The Bachelor, and Sam proposed with a 2-carat diamond engagement ring just three months after the show ended in December 2015.

Shortly after, they purchased a $1.4 million home in Melbourne and moved in together with Eve.

While rumours of a secret wedding have been brewing for months, in January, Sam told TODAY the pair were hoping to finally wed this winter.

"Snez likes to change her mind, so we're jumping all over the place," the fitness guru said. "She's now decided she wants an overseas wedding…That's on the cards. She's Macedonian so we're looking for somewhere in Europe in the middle of this year."

Congrats, Snez and Sam!
