Andy and Bec met approximately five-years-ago when Bec was working as at a Melbourne cafe frequented by the radio presenter. They decided to move in togetheraround Septemeber 2017.
The comedian revealed on his popular radio show Hamish & Andy that he sparked instantly with Bec whilst she was waitressing part-time as a student. “I caught her eye and I was attracted to her. Just the way she was treating other people, she had a lovely demeanour,” Andy told his radio co-host Hamish Blake back in 2015.
“I was trying to chat to her, so I was ordering a lot. I had like an hour and a half breakfast and you know I don’t really like that because I like getting in and out in food situations.”
He ended up leaving his email address on a napkin for her.
With interest in their relationship rife, both have spoken about the possibility of getting hitched. But sorry guys, Andy won't be asking Bec to marry him until she does this one thing: Lee recently confessed that he wouldn't pop the question to Bec until she tells him about her high school results.
"Well, I've got a funny thing with Bec. Bec has never told me her enter score, what she got when she finished year 12," he said on KIIS 101.1’s Jase & PJ in August.
"So I said to her, if you want to be proposed to, we can't have any secrets. So the day you tell me your enter score, is the day I'll know you're ready."
