Katie Couric has got engaged.

The 'Katie' talk show host's boyfriend, 50-year-old banker John Molner, proposed with an impressive diamond ring over the weekend and she had no hesitation in saying ''yes''.

A representative for Couric, 56, has confirmed the happy news to People magazine and revealed Molner popped the question as the sun set on the beach in East Hampton, New York.

Couric and Molner have been in a relationship for nearly two years and they publicly confirmed their romance in April 2012.

Later that same year, she gushed about the banker - who is head of mergers and acquisitions at Brown Brothers Harriman - saying: ''He's great. He's from Chicago. I love Midwesterners!''

Former 'Today' host Couric was married to Jay Monahan, but she was widowed when he tragically died from colon cancer in 1998 at the age of 42.

They had two daughters, Ellie, 21, and Carrie, 17, together and after Monahan's death, Couric became a spokeswoman for colon cancer awareness.
