DJ/music producer Mark Ronson has reportedly proposed to his girlfriend, French singer/actress/model/It girl Josephine De La Baume. Purple Diary, the blog of Purple magazine, posted this photo of De La Baume sporting an engagement ring with the caption “Josephine de la Baume with the engagement ring that Mark Ronson has recently give [sic] her.” It could be the real thing, although De La Baume and Ronson have played around with fake rings before, most notably in a Jalouse magazine photo shoot where they pretended to be newlyweds. Jalouse? You bet I am.
