They’re a high-profile couple in the fashion industry, but it looks like Marc Jacobs and Lorenzo Martone may be calling it quits.

According to a report, Martone was nowhere to be found during Marc’s speech at the CFDA Awards on Monday night, and it may have something to do with Lorenzo’s bad behavior last week.

Back out just one night after attending the MTV Video Music Awards, Lady GaGa was on-hand for the Marc Jacobs 2010 Spring Fashion Show at the NY State Armory on Monday night (September 14).

Joining up with Madonna (who was out with beau Jesus Luz) and Marc Jacobs for a few photo ops, the "Poker Face" singer then headed along on her way to check out the latest styles from the popular designer.

The MET Costume Institute Gala was a star-studded event to be sure, and afterwards the attendees were ready to party.

Hotties like Bar Refaeli and Miranda Kerr were spotted heading over to the Monkey Bar for a swanky after-party hosted by Marc Jacobs.
