When Tinder execs were all sat around a big long table (bet it's mahogany gloss), putting their guest wishlist together for their Swipe Sessions, we reckon J-Lo was right up there (along with Swifty, obvs).
Some would call her an expert in the dating game - she's been married (three times to be exact), has dated the likes of Sean Combs (P. Diddy/Puff Daddy/Diddy/Love/make your mind up mate), Ben Affleck and in 2016 she was linked to rapper Drake.
So, we feel she's a reliable source when she says that guys under 33 are 'useless'. Drake was 30 when the pair were an 'item', and let's not forget 24-year-old Casper Smart, who she started dating in 2011 - when she was 41.
The new episode of Tinder's Swipe Sessions saw Lopez help Brooke, a 29-year-old country singer. The pair swiped their way through a few potential candidates while J-Lo made sneaky remarks as she went.
The singer, actress and dancer flicked through a few men and dismissed them all. Until she came to Maurice. Maurice looked like a lovely chap.
He was 29 and a social media manager who lived four miles away. He was drinking a glass of wine in his profile picture. Win-win in our eyes.
But J-Lo had to come and rain on everyone's parade as she remarked: "Guys - until they're 33 are really useless". The cheek.
Then the search turned to Daniel, a 27-year-old university student.
Giving an insight into his life, Daniel's bio read: "If you store ketchup in the refrigerator, we're not going to work out." Mature.
It was a no-no from J-Lo: "Bye, bye him."
We may mock, but the mum-of-two is wise. "I've had blind dates, hooked up with some real flakes," she once sang.
"I've gone out with church boys, musicians are the worst. I've tried so hard, 'cause I'm just so die hard". See, she knows her stuff.
Wonder who the church boy was? Hazard a guess at Wesley Snipes?
And here's the evidence that taking her advice is probably the way forward because it's pretty fucking solid. Business Insider spoke to Dr Jane Greer, a New York-based relationship expert.
She said: "It can take men into their early 30s to establish their professional career and feel a sense of financial stability, which helps them feel more secure in life.
"As a result, this can give them the maturity that comes with accomplishment, experience, and success."
And correctly preserved ketchup.
