Katie Couric is engaged.

Financier boyfriend John Molner popped the question at sunset in East Hampton with "spectacular diamond" Couric's rep confirmed to People Magazine.

Couric and Molner, 50, have been dating for nearly two years.

Couric, who returns to the second season of her talk show "Katie" on ABC, went public with their romance in April 2012.

Yes it's true! So touched by all the kind Tweets & warm wishes-thank you! A great end to the summer & looking fwd to seeing you all Monday!!

She has two daughters, Ellie, 21, and Carrie, 17, from her marriage to Jay Monahan, who died of colon cancer in 1998.

The 56-year-old TV personality dated several men after his death, but never seemed to find the one to settle down with again.

"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," she told More Magazine in January. "I always wanted a father figure for my daughters, but it hasn't worked out that way. I've had long-term relationships, but they haven't turned into life-long partners."

Couric was romantically linked to TV producer Tom Werner and financier Brooks Perlin. But dating isn't easy, even for a famed TV journalist.

"Also, when you get to my age, everyone is a bit wounded. So I think it's important to handle people with care--not to think, 'Oh, what a terrible date,' but just, 'This person isn't for me,'" she said. "Everyone has a lot of baggage. It's just can you fit it into the overhead bin?"
