Lovebirds Lorenzo Martone and Marc Jacobs
Ladies, remember those "Girls Love Marc Jacobs" ad campaigns? Well, he's off the market. Like, way off the market. Like ... engaged to a man off the market.

The lucky man, Lorenzo Martone, is a hottie Brazilian ad executive who's been dating Marc Jacobs for about a year. The news will be hitting the public today, Thursday -- they are planning to de-plane in Brazil wearing engagement rings!

We girls still love Marc Jacobs. Congratulations!

We are currently drooling over the "It" Marc Jacobs Palais Royal Asa purse, a crazy great, springy pink crossbody. For more awesome Marc Jacobs finds, and to show your support, check out the "something blue" items for men below!
