And if truth be told, they've both got a great set of lungs on them!
JLS' Marvin to propose to Rochelle?
The Saturdays star says it will happen when the 'time is right'.
The pair have been dating for a couple of years, despite a brief break-up, and now people are wondering if they're going to take their relationship to the next level.
Rochelle said: "Everyone that's with their boyfriend in a serious relationship, if their boyfriend said lets get married, you know you're not gonna be with them if you're not, you know...".
The Ego star explained that even if she thought the all important question was around the corner that she wouldn't ever go snooping in drawers looking for a shiny rock.
"I always think it's something you should never ask and never talk about, when it happens it happens, and I don't like to talk about it 'cause you can jinx stuff in life.
"When your other half, not just me I don't wanna talk about myself, but your other half thinks it's right and they want to propose to you they will do that."
