The former X Factor contestants put on a loved up display at the London television studio on Monday morning (13 July), shortly after announcing their plans to marry.
Stevi and Chloe-Jasmine are the first X Factor couple to become engaged – just months after meeting on the last series of the ITV show.
Their engagement was announced at the weekend, with Stevi tweeting: "Hi everyone we are very pleased to announce that me and @CHLOEJASMINEW are engaged I am over the moon thank you peeps."
Chloe-Jasmine, meanwhile, told The Sun she'd already been in touch with her X Factor mentor Cheryl Fernandez-Versini.
"I sent Cheryl Fernandez-Versini a message to thank her for bringing this amazing person into my life. She texted back saying congratulations, and she was so happy for us both. I'd definitely invite her to the wedding if she wanted to come."
The couple appeared on ITV's Lorraine last month to speak about their romance. They met on X Factor last year and became friends, before a relationship blossomed just before Christmas.
Chloe-Jasmine said: "It's so strange people say [we are an unlikely couple] and we don't understand that at all. It's not like he's dating a panda! It's a quite a normal relationship."
Stevi said: "I always wanted to find love but I never expected it would be with Chloe. I mean the first time I saw her I looked at her, I was like, 'you're funny but not my cup of tea.'"
