She said: "We're older now, we're smarter, we have more experience, we're at different places in our lives, we have kids now, and we have to be very conscious of those things."
Jennifer and Ben's romance created huge interest in the early 2000s. But the On the Floor hitmaker is convinced they will both be able to cope with the pressure this time around.
Jennifer - who has also been married to actors Cris Judd and Ojani Noa - explained: "I think we are strong enough now to know what's real and what's not, whereas when we were younger maybe some of those outside voices were a little bit tougher for us to reconcile and survive."
OMG! I finally got the #onthejlo email! I am so FREAKING HAPPY for you @JLo !! So happy for Ben, you and your families! True LOVE & real LOVE does exist and you both found it in each other!!
