Kate, the Princess of Wales, is recovering after undergoing abdominal surgery that will leave her hospitalized for as long as two weeks, according to Kensington Palace.
A palace source told ABC News Thursday that Kate is doing "well" in her recovery.
Kate, 42, was admitted to The London Clinic on Tuesday for a "planned" surgery, Kensington Palace announced Wednesday.
The surgery was "successful," according to the palace, but Kate, the wife of Prince William and mom of their three young kids, is expected to remain hospitalized for 10 to 14 days before returning to the family's home to recover.
The palace did not provide further details on the type of surgery Kate underwent, but confirmed to ABC News that the princess's medical issue is non-cancerous.
The palace noted that Kate's hospitalization means she is not likely to resume her public duties "until after Easter."

"She hopes that the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private."
"The Princess of Wales wishes to apologise to all those concerned for the fact that she has to postpone her upcoming engagements," the statement continued. "She looks forward to reinstating as many as possible, as soon as possible."
While Kate recovers, William has postponed his engagements to help care for her and their kids, according to the palace. Neither William nor Kate will undertake any international travel in the coming months as well.
Kate's last public appearance was on Christmas Day, when she joined members of the royal family for their traditional Christmas morning service at Sandringham, the royal family's estate in Norfolk, England.
