O'Donnell, 50, who recently suffered a heart attack, moved up her planned wedding to fianceé Michelle Rounds after Rounds was diagnosed with desmoid tumors, a rare disease that only affects three out of every million people.
The couple, who announced their engagement in Dec. 2011, exchanged vows on June 9 in a private ceremony in New York, O'Donnell's rep Cindi Berger tells PEOPLE exclusively. "They got married but they haven't had the wedding celebration."
The two originally planned to be married in August, but they choose to get married quietly in June before Rounds's first surgery on June 14.
"It is such a rare tumor. It took them quite a while to get an accurate diagnosis," adds Berger. "She had several gastrointestinal surgeries to remove the desmoid turmors. She is now on the road to recovery."
O'Donnell, meanwhile, took to her blog to share the happy news.
"We married in private before [Michelle's] surgery, just the [two] of us," she wrote. "When we r both well enough will have the wedding of r dreams surrounded by those we cherish."
"Thankful for the love and support so many have given us during these trying times," she continues in the post. "Including all of u stranger-friends connected thru invisible strands of wi fi."
O'Donnell and Rounds hope to raise awareness for desmoid tumors by participating in the annual DTRF Running for Answers 5K, held in Philadelphia on Oct. 21. They are raising funds and plan to match all donations made to Rounds's fundraising page.
