London, Aug 3 : Justine Timberlake is so worried about his ladylove Jessica Biel's thin frame that he's ordered her to go on a burgers and beer binge.
"Jessica really loves to work out and so does Justin, but lately it seems like that's all she is doing," the News of the World quoted a source, as saying.
"Justin is trying to get it through to her that she can take some time out to enjoy burger and beers," the source added.
Meanwhile, rumours are rife that the hunky pop star is hunting for the perfect ring for his girlfriend.
The '4 Minutes' singer is also reportedly eyeing many exotic islands as a venue for his marriage to Biel.
