>> INSIDER WIRE —On the same day Marc Jacobs announced his engagement to Lorenzo Martone, he also bought a house to share.  Apparently, the couple has been looking a downtown New York properties for a while, and finally settled on a $13 million, 4,500-square-foot West Village townhouse on Bethune Street — with private garden and roof terrace — designed by Robert A.M. Stern.  Sounds like Marc is now the proud owner of one of these babies. [Page Six]
