Jimmy Fallon and Nancy Juvonen: Engaged!

Sorry, Caroline D'Amore and Matthew Ross: you're no longer the most random Hollywood couple to get engaged this week.

Jimmy Fallon popped the all-important quesstion to Nancy Juvonen, a Hollywood producer who worked on Fallon's 2005 romantic embarrassment comedy Fever Pitch.

The proposal took place in New Hampshire "last weekend on the dock at sunset at the Junoven's family home in Wolfeboro on Lake Winnipesaukee, where On Golden Pond was filmed," a friend of the couple told People magazine. "He presented her with a one-of-a-kind ring designed by Neil Lane."

We assume, unlike that of Heidi Montag, this piece of jewelery is real.

The bride-to-be has been a close friend and producing partner of Drew Barrymore's for more than a decade. Earlier this summer, that actress threw Juvonen a 40th birthday party, where guests included Eva Mendes, Kathy Griffin, Courtney Love, Jason Bateman and Fred Savage.

It's the first marriage for both.
