What an inspiration! Jamie-Lynn Sigler wants her fans to know one thing: “I have MS and I am still strong.” The Sopranos star proved that she’s not letting the formidable disease dictate her life after she took to Instagram on Monday, April 15, to share two transformation pics of her post-baby body since welcoming her second son, Jack Dykstra, in January 2018.

“This was five months postpartum … and then the second photo was in January,” the 37-year-old captioned the post including a before and after photo. “I do strength training two to three times a week on a rug in my home. That’s it. Also, it is NOT about being skinny. I could care less. This hard work is what keeps all my professional and personal dreams alive.”

The Guys With Kids actress — who is also the mom to her 5-year-old son, Beau Dykstra, with husband Cutter Dykstra — first opened up about her multiple sclerosis diagnosis in January 2016. At the time, Jamie candidly revealed she’s been living with for 15 years.

“I want to live my truth,” the Wise Girl author told People at the time. “I don’t want to hold a secret where it feels like I have something to be ashamed of or I have something to hide.”

Most recently, Jamie-Lynn opened up about being a mom and the extremely difficult conversations she’s been forced to have with her husband and sons as a result. In an extremely heartbreaking essay she wrote for Shondaland.com, the brunette beauty revealed how the couple has been preparing against the devastating illness.

“Sadly, [I’ve] had to have the talk with my husband about what we’d do in the worst of circumstances, where I thought out loud: If there ever was a mass shooting, you have to take the kids and run, and trust I will do my best to stay safe,” she penned, explaining that MS limits her movement. “Just thinking about this still makes me tear up.”

She elaborated that since chronic illnesses like MS become “your whole family’s disease, not just your own,” becoming a mom and having children has been a difficult and tumultuous road. “I had to think about how my MS would affect someone else,” she confessed, adding that her hubby “has made me feel since day one that this disease had no negative effect” on them as a couple. “But with my son, his safety depended on me! His survival!”

Although each day is “not without its challenges,” the ferocious mom-of-two isn’t letting MS hold her back. And it seems like she’s never looked — or felt — better! Way to go, lady!
