Are the Roloffs expecting another little one?

On Monday, Matt Roloff took to Instagram where he hinted very big news was on the horizon.

"The Roloff family has greatest news ever to announce!!!! Later today we tell you all about it!!!!" Matt revealed.

The post comes on the heels of Matt and Amy's oldest child, Molly, paying them an unexpected visit.

"The Amazing Molly Jo was in town for a surprise visit this weekend at the same time my folks were in town," Matt said in another post. "What a fun Sunday! Hope You all had a great relaxing day too!"
