Sam popped the 'girlfriend' question to Georgia during an appearance on Good Morning Britain and she was quick to accept, revealing they are already planning on moving in together.
The pair then shared a kiss and a cuddle in front of delighted hosts Charlotte Hawkins and Kate Garaway – and millions of viewers at home.
Sam and Georgia quit the Love Island villa last week after being told to either recouple with new islanders or leave.
The pair decided to walk so they could continue with their blossoming relationship.
During their GMB interview, Sam told Georgia: "Obviously we're been through a lot, both inside the villa and outside the villa and we've going to be living together, so I wanted to know if you'd be my girlfriend?"

Georgia then threw her arms around Sam and kissed him, as Kate and Charlotte squealed with joy.
GMB's showbiz correspondent, Richard Arnold, was sat next to the couple at the time and joked: "Hello?!"
Sam replied: "Don't worry, you can come to the 'loyal' wedding, that's fine!"
They were back on TV just hours later with an appearance on This Morning, and Sam opened up about their plans to move in together.
He revealed he's leaving his hometown of Norwich and moving to London to set up home with his new girlfriend.
Sam said he's looking forward to have a "normal" relationship, while Georgia said she's planning lots of romantic nights in with TV and takeaway dinners.
He said: "I want to move to London and live with Georgia so we can be together…
"At the end of the day I want to come home and spend time with her, like normal."
Last week, Sam and Georgia found themselves with a difficult choice to make following a live public vote, which saw them come in the bottom two.
Their fellow islanders also voted for them to leave, however they were thrown a lifeline by show bosses.
The couple were told they could stay on the island providing they split up and each recoupled with someone new.
