She’s gaining another daughter! Amy Roloff, who stars in TLC’s Little People, Big World, is mom to four kids and now that her children are older and marrying off, the Roloff family is getting even bigger. Amy took to Instagram to gush over her son Jacob Roloff‘s fiancée Isabel Rock and it seems like she can’t wait to welcome yet another daughter in law into the family.

“I love this girl that Jacob asked to marry him,” the 53-year-old wrote in the caption of an adorable selfie with Isabel. “We have a great time hanging out and talking. Excited to go to her art event at Abbey Creek Winery in North Plains tomorrow. So proud of her! I’m a blessed mom — all my DIL’s are awesome, doing good things in life and they inspire me too. You rock, Isabel.”

It’s so sweet to see Amy be so supportive of Izzy’s art — especially because she seemed to be nervous about this particular show. Earlier this week, Isabel tweeted, “70 people might show up to my art show tomorrow and I am suddenly SO NERVOUS AND ILL PREPARED I FEEL LIKE.”

But Amy isn’t the only one who’s supportive of Izzy. Last month, Jacob shared a photo of his fiancée on Instagram and gushed over her art show. “Sooooo, I’m very proud of Izzy. She’s been booked for a show (ENVISION) at the Roseland Theater here in Portland, put on by RAW Artists; she’s one of 36 visual artists from the area,” he wrote.

Like Jacob, Izzy is definitely a creative person — even though Izzy is more visual and Jacob uses writing as a creative outlet. But they both appreciate photography and the couple’s Instagram pages are full of gorgeous photos that they’ve taken themselves — and usually are from the couples’ adventures together, like their recent vacation to Iceland where they got engaged.
