The New York Police Department said police have found the happy couple and are working to return the engagement ring after it fell down a utility grate.
Drennan told the newspaper they had planned to keep the lost ring a secret, but a friend forwarded him the police Twitter message.
Shortly after proposing in New York City, a man accidentally dropped his fiancé's engagement ring down a NYC grate in Times Square.
But just moments after they touched down at the airport, a friend alerted them to the social media campaign being driven by the New York Police Department.
Emergency Service Unit officers responded but didn't immediately find the ring, so the couple left.
NYPD is expected to release more information later Sunday.
After seeing the footage officers managed to rescue the ring, clean it up and now want to find its owners.
The ring was lost on Friday night and NYPD recovered it ring Saturday morning.
They also posted a photo of the ring itself.
Police on Saturday afternoon tweeted surveillance video of the couple in Times Square, with a message: We have the ring. "I hope the couple is found soon", a Twitter user wrote.
The NYPD blasted out the tale on social media hoping to track down the couple to give them the good news, and on Sunday Drennan, already back in the United Kingdom, reached out to the Crimestoppers hotline.
