In fashion, one day you're in, and the next you're engaged.

Christian Siriano, winner of Project Runway's fourth season, will tie the knot with his boyfriend of six years, Brad Walsh.

The happy couple exchanged bracelets instead of rings, sharing the news and showing off the new bling on Twitter and Instagram.

"We've told our moms so now we can tell you," Brad writes.

Having won Project Runway in 2008, Christian launched his self-titled fashion line in 2010.

Meanwhile, Brad is a visual and recording artist best known for his photography and his remixes of songs by Lady Gaga, Beyonce, Rihanna, and more pop stars.

So happy to hear of the good news. Now, will Heidi Klum be the best man?
