The boyband hunk has apparently been ring shopping already.
Rochelle's been on holiday in Portugal with mates, and so sneaky Marvin took the opportunity to secretly hunt out an engagement ring.
"Marvin’s booked an appointment at Tiffany & Co," a friend of the JLS star revealed.
"That’s where he bought her the commitment ring when they got back together."
The couple have been together on and off since early 2010 but with their busy work schedules finding time to pop the question isn't easy, so Marvin's planning to wait until they both get a break together.
"They’ll be going to the Maldives on holiday in the New Year, and that’s when friends think Marvin’s going to propose," the source told Heat magazine.
"They’ve been working really hard, so this will be the first chance they’ve had for a holiday."
