"My girl and I," Cate captioned the image alongside a red heart emoji.
This comes on the heels of her and Tyler's controversial pregnancy prank when they teased they were expecting a sibling for their two-year-old daughter, Novalee, earlier this month. Many fans felt this was too sensitive of a subject to joke about, which Ty wound up addressing on Twitter.
"Apparently, the world can’t take jokes anymore. Don’t worry #TeenMomOG will be back on the air soon so we can disappoint you some more,” he wrote at the time.
His wife previously revealed that she is hoping for a son this time around, though on last night's season premiere she admitted she's nervous to have more kids and suffer again from postpartum depression.
“If the next one is a boy, I’m done. If it’s not, then we’ll probably try for a third but I’m done after that,” she said during a Facebook Q&A back in 2015.
