'Real Housewives of Orange County' Star Emily Simpson Shares Update on Son Luke's Eating Disorder 

Emily Simpson is sharing some good news about her son, Luke.

The Real Housewives of Orange County star spoke with E! News at the show's season 20 premiere party in Los Angeles on Tuesday, where she revealed that the 11-year-old is doing better than ever.

"He's doing much better," Simpson said of Luke, who struggles with developmental issues, including the rare eating disorder ARFID (Avoidant/Restrictive Food Intake Disorder). "He goes to a new school now, so we've really found what works for him."

That's also translated to life at home, with Simpson revealing that she and husband Shane Simpson, with whom she also shares Luke's twin, Keller, as well as daughter Annabelle, 12, have also made adjustments to navigate Luke's anxiety, ADHD, and OCD.

"We've had to parent differently," the 50-year-old reality star shared. "He's completely different than the other children, he has different needs."

Simpson shared Luke's struggles on the show, and while it was emotional, at first, for the mother of three to open up about what her son had been going through on national television, the former attorney now says she's "so glad" she did.

"I am so glad that I shared about him," Simpson said, a sentiment that rang especially true after learning that his health issues were potentially linked to PANDAS, or pediatric autoimmune neuropsychiatric disorders, a group of symptoms associated with streptococcal infections in young kids.

"I still, a year later, get DMs from moms saying, 'I didn't know about PANDAS, now I know. I took my kid to the doctor, they got a diagnosis. You're the reason I did that,'" Simpson told the outlet. "I'm not talking one, I'm talking lots and lots and lots of messages."

She continued, "So, even though I struggled with how much to share, because he is my child, I'm so glad that I did."

As for the rest of her family life, the RHOC star promised everything is just fine in the Simpson household, despite the show's Season 20 trailer, which signaled trouble in paradise for her longtime marriage.

"Shane and I are still together," Simpson told E!. "I think we're just two people that have been married a long time, it will be 18 years soon. Navigating life and marriage and cameras and kids and a blended family and dogs and cats and a house and we irritate each other."

See it all go down when The Real Housewives of Orange County returns July 9 at 8 p.m. ET on Bravo.
