Katie Couric is a married woman again after exchanging vows with financier John Molner at her East Hampton, Long Island home.

The couple wed in front of 50 guests, including Molner's two children and Couric's two grown daughters from late husband Jay Monahan, who passed away of cancer in 1998.

"So excited to make my debut as Mrs. John Molner!" the former TV newswoman tweeted along with a photo from the wedding.

"We wanted to keep the wedding just very low-key," she told People magazine. "This is not my first rodeo so I didn't want to go too crazy and neither did John."

Couric, 57, currently works online for Yahoo News. Molner, 51, is a partner at Brown Brothers Harriman, which is the oldest private bank in America.

The couple began dating two years ago.
