Vowing to fight her rare form of cancer, Jen Arnold, star of TLC's The Little Couple, has decided to let cameras document her ordeal.
"TLC has chronicled Bill and Jen's lives since 2009 and at their request, we will be following them through this challenge," a TLC spokesperson tells PEOPLE. "Jen is a doctor and teacher and she saw this as an opportunity to educate and possibly help, through sharing her story."
Arnold, 39, is a neonatologist at Texas Children's Hospital where she serves as medical director of the Pediatric Simulation Center and an assistant professor of pediatrics at Baylor College of Medicine.
She is "currently undergoing treatment, including surgery and chemotherapy," she told PEOPLE Thursday.
It's more formal than their adorable save-the-date card. But Sean Lowe and Catherine Giudici's official wedding invitation still captures the spirit and personality of the fun-loving couple.
The invite, shared exclusively with PEOPLE, has "the LOWEdown" on "marrying, eating, boogie-ing," and goes on: "Together with their families, Sean Thomas Lowe will marry his best friend, Catherine Ligaya Mejia Giudici, who completely adores him."
The invitation, designed by Smitten on Paper, includes an RSVP card for recipients to declare whether they "can't wait" or have "something more important to attend than celebrating the union of Sean & Catherine."
It's hard enough for The X Factor judges to say goodbye to one of their contestants during an elimination show, but on Thursday night Demi Lovato was devastated when her two remaining team members – Ellona Santiago and Rion Paige – were eliminated.
"I'm actually pretty speechless and disappointed," said an upset Lovato after learning that Santiago, 17, would be the first contestant going home. "She could've won this competition."
Lovato wasn't the only one who was shaken by Santiago's elimination. Fellow judge Kelly Rowland looked surprised, with her eyes and mouth opening wide and her hand placed on her heart as she stared at Santiago in disbelief.
Host Mario Lopez's voice also softened as he said it was "a real shock here on the stage and in the audience."
Jen Arnold, star of the hit TLC series The Little Couple, is battling a rare form of cancer.
The Houston-based neonatologist, 39, and her husband Bill Klein, 38, are parents to son Will, 3, whom they adopted from China, and daughter Zoey, 2, whom they recently brought home from India.
But what should have been a time of joy and celebration for the reality stars has been bittersweet, as Arnold reveals in an exclusive statement to PEOPLE.
NBC's Sound of Music Live!, starring country star and American Idol winner Carrie Underwood as trilling, hill-hiking governess Maria von Trapp, was like a snow globe with scarcely any flakes.
You could turn it upside down and shake it, really shake it, but no magic ever swirled around that plastic Alpine scene.
I can't imagine it supplanting the 1965 movie, with Julie Andrews singing of warm woolen mittens and larks learning to pray in a voice so purely crystalline it can induce brain freeze.
