The singer-and-actor got the body art during their first year of marriage so whenever he, and anyone else, sees it they know he is taken.

Marc said: "It's so I can see it, and when I'm on stage everyone can read it."

Jennifer added: "He's had that for a while."

The "Do It Well" singer married Marc in June 2004, just four days after his divorce from first wife, former Miss Universe Dayanara Torres, was finalized.

Earlier this month, Jennifer sparked pregnancy rumors when she sported an apparent baby bump under a loosely-fitting green dress at her catwalk show during New York Fashion Week.

It was then reported she and Marc - who are said to have turned to IVF treatment after struggling to conceive naturally - had gone for their first ultrasound scan, suggesting the 38-year-old singer is 12 weeks into her pregnancy.

J.Lo further fueled speculation by announcing she plans to take an extended break after her first full scale tour later this year.
