Jennifer Lopez is opening up about why her two previous marriages didn't work out -- and how she keeps the love alive with hubby Marc Anthony.

"I'm still figuring it out as I go along," Lopez admitted of her marriage, adding, "This is my third time. I don't even think I tried in my other marriages, which was immature... I believe that in life you learn through experience. I'm old enough to know now that relationships take work. That it's not an easy thing."

Lopez and Anthony tied the knot in June 2004.
