Lopez, who is now on her third marriage, celebrated her anniversary with the Latin singer last Sunday.
The stars, who were involved several years ago as well, shocked Hollywood last year with their secret wedding. Additionally, the marriage came only four months after the Lopez ended her relationship with actor Ben Affleck.
A family friend says, "It sounds a little odd, but Marc and Jennifer were never really engaged – they just got married. So, to mark their first anniversary, Marc officially proposed, this time presenting Jennifer with an engagement ring from exclusive jeweller-to-the-stars Neil Lane.
"It’s huge, and it sparkles beyond belief. Jennifer was very excited to get it." , the friend added.
