Katie Couric, 56, has finally found love again.

 The talk show host and mother of two, who lost husband Jay Monahan to colon cancer in 1998, got engaged to financier John Molner, 50, over the Labor Day weekend.

"Katie's calling it her labor of love," said People editor Larry Hackett on Good Morning America announcing the news.

Molner, head of mergers and acquisitions at Brown Brothers Harriman, popped the question with a diamond ring at sunset on the beach in East Hampton, N.Y., reports People.com.

Katie told me in May she and Molnar were "having a great time. He's really funny and very successful in his own right. In a different line of work. A little more age appropriate."

How old is he? "He's six younger than I am," said Couric, who has dated younger men in the past including trumpeter Chris Botti (5 years younger) and entrepreneur Brooks Perlin (17 years her junior). "But hey, I've got a lot of energy, you know. I need someone who can keep up with me!"

Maybe since daughter Ellie, 22, just graduated from college and daughter Carrie, 17, is a senior in high school, the timing seems right at home. In the February issue of More magazine, Katie admitted, "It's actually surprising to me that it has been almost 15 years and I haven't remarried. I think life is more fun when you have someone in your life."
