Reckon guys really mature more slowly than women?

Depending on where you stand, you'll think this is an indisputable fact or a sexist generalisation. Jennifer Lopez clearly falls into the first category, having gone on the record that men are only worth dating past the age of 33. In a Youtube video for Tinder, J-Lo helps a girl called Brooke with the app. Swiping left and right through Brooke's potential matches, the singer vetoes a guy called Maurice because he's only 29. "Guys until they're 33 are really useless," she explains as she swipes left. Harsh - but then J-Lo does have plenty of experience when it comes to relationships, so maybe she does know what she's talking about. The 49-year-old recently got engaged for the fifth time. Her boyfriend of two years Alex Rodriguez got down on one knee earlier this month. Alex, 43, will be J-Lo's fourth husband. She was married to Ojani Noa from 1997 to 1998, Chris Judd from 2001 to 2003 and Marc Anthony from 2004 to 2014. She and Marc are parents to 11-year-old twins Maximilian and Emme. Jennifer also got engaged to Ben Affleck in late 2002, though they called off the wedding the following September.
