The girl group - who will open for the US star's two UK shows in October - admitted that they are hoping to get some advice from the singer when they meet her.
Asked by Capital FM if they will be seeking some tips, Courtney Rumbold said: "She's a legend, definitely, you forget how long she's been in the industry and how much she's done."
Rumbold also joked that after supporting Nicki Minaj earlier this year and with their Lopez slot next month, the trio have been supporting the popstars with the most famous bottoms.
"That means we've supported two women with the biggest bums. It's so funny, it's like a running trend," she laughed.
Jennifer Lopez will headline London's O2 Arena on October 22 and Manchester Arena on October 23.
