Twice as nice! Jaime King announced via Instagram on Thursday, Feb. 19, that she's expecting her second child with husband Kyle Newman.

The Hart of Dixie actress, 35, shared a photo of her 16-month-old son James Knight blowing bubbles in a field. On his lap is a sign that reads: "I'm gonna be a big brother! Who da boss now. I'm so excited!!!!" Indeed, little James looks enthused as he holds up the bubble wand and makes a wish.

"So excited to announce THE SEQUEL Coming later this year!!" King wrote alongside the photo of her son. "#BabyTown2 - Created by @kyle_newman and @jaime_king. Also starring #JamesKnight."

King and her director hubby tied the knot in 2007, and welcomed their son in October 2013. Before welcoming her first child, King faced massive fertility issues, and detailed her eight years of struggle to conceive last summer, when James was 9 months old.

"8 yrs of pain & undiagnosed PSOC [Polycystic ovary syndrom] & Endometriosis," she wrote on Instagram. "5 miscarriages, 5 rounds of IVF [In vitro fertilization], 26 IUIs [Intrauterine insemination], most with no outcome, 4-1/2 years of trying to conceive, 26 hours of brutal labor, early delivery b/c of sudden preeclampsia, tearing and tearing after the stitches were in once I was home."

The arduous journey, however, was worth it for the star who told Us Weekly last September that there was nothing more rewarding than being a mom. "It's the best thing in the whole world," she gushed to Us.

At the time, King's Hart of Dixie costar Rachel Bilson was expecting her first child with Hayden Christensen. (The stars welcomed their daughter Briar Rose in October.) "Enjoy it," King advised her costar of pregnancy. "Be gentle on yourself. Be easy on yourself. It's a wild ride. Listen to your own intuition. Do as much research as you can but there's no right. There is no wrong."

Indeed, babies are taking over the Hart of Dixie set, because their costar Scott Porter also announced earlier this month that he and his wife are expecting a son.

"Little guy is going to have a tough time deciding who to root for...but we'll love him not matter what school he chooses...right @kiwiporter?" the Friday Night Lights alum, 35, wrote. "#housedivided #PorterOnTheWay."
