Andy Lee revealed on Thursday the harrowing moments he and fiancée Rebecca Harding almost lost the very flashy diamond ring he proposed to her with.

The duo finally got engaged after 10 years of dating when the radio host, 43, dropped down on one knee on April 28.

But their happy union almost came crashing down when Rebecca, 33, had a 'near miss' with her diamond twice, Andy revealed on LiSTNR's Hamish & Andy

The media personality explained the ring was too big and had to be resized, so Rebecca spent the week following the proposal trying not to lose it.  

However, he said: 'Two points where it came off, first one at my sister's place. It's come off while she's very excited explaining what's happened. It's flung off.'

'She felt it come off. We all watched it in slow motion in the air. Our dog [Henri] loves eating anything that hits the ground. It hit the ground,' he continued.

'It's jingling along and Fred, my nephew, slid in on his chest and beat Henri to the ring.'

Unfortunately, that wouldn't be the only time Rebecca's extravagant diamond ring came flying off her finger.

Andy said: 'Here's the second one. We'd been celebrating again and we got home. Bec's gone to the toilet. I've heard, "Clink, clink, clink. Oh no, Andy!"

'She said I'm never allowed to tell this story, but it's been a month. I get in there, it's in the toilet. She's dropped the ring in the toilet. Just number ones.'

The comedian went on to reveal Rebecca did the unthinkable and stuck her hand into the urine-filled water of the toilet to fish out her engagement ring. 

Andy announced he popped the question to Rebecca on his Hamish and Andy podcast on May 1, following ten years of dating.

Rebecca also shared an update to her Instagram account while showing off the stunning diamond engagement ring. 

'People keep saying we’ve rushed into this but we don’t care what people say!' she wrote, poking fun at the years of speculation surrounding their engagement. 

Andy and Rebecca met in 2014 at a Melbourne café where she was working as a waitress. They went public with their relationship at the 2015 Australian Open.
