The TV presenter's fiance James Midgley popped the question during the trip last weekend.
Jenni, 33, said: "It was incredibly romantic and was a gorgeous, warm evening - the lights of Manhattan shone in the distance and we had a band playing live music on a boat."
She went on: "I'd been laughing so much all evening, I was genuinely surprised by James's proposal.
"I did hope I'd be romanced, but never expected a gesture like this.
"In saying that, I was delighted to be asked - and of course my answer was a definite yes."
