Marvin Humes and Rochelle Wiseman have weekly date nights
The JLS hunk believes the reason why his relationship with the Saturdays singer is so strong is that they strive to find the time to be together without any distractions.
Marvin told Closer magazine: "Me and Rochelle have one night a week when we go to the cinema or cook a meal for each other."
Marvin`s bandmate, JB Gill has been in a relationship with dancer Chloe Tangney for three years and credits their happiness to "surprises".
He said: "I like surprises - just little things you`re not expecting."
The pair`s other bandmates, Aston Merrygold and Oritse Williams are currently single but both have their eyes on high-profile women as ideal partners.
Aston said: "I like Mila Kunis at the moment."
Oritse added: "Rapper Nicki Minaj is my ideal girl. She`s got all the ingredients I love - an amazing bum, lips, talent and personality."
