Humes and his girlfriend Rochelle Wiseman from The Saturdays are planning to find the 22-year-old "good girls" he can date, The Mirror reports.
"Aston may be a hottie, but he hasn't had the best luck with the ladies. He used to have the best pulling machine with Marvin as his wingman," an insider said. "But now Marvin is loved-up with Rochelle and he wants the same for his best mate."
The pair even plan to chaperone Merrygold on his dates but have already ruled out certain girls for the singer, who has previously been linked to former WAG Sophie Houghton and ex-Eastenders actress Louisa Lytton.
"No Twitter freaks are allowed. They don't want any more kiss and tweets," the source revealed.
JLS are on course to top the UK singles chart this weekend with 'The Club Is Alive'.
