Congrats to Cobra Starship frontman Gabe Saporta! The singer tied the knot with fashion designer Erin Fetherston yesterday (May 26).

"The couple chose to tie the knot in the gardens of the historical St. Nicholas Abbey plantation," a rep revealed to Us Weekly. "Fetherston wore a gown of her own design, and Saporta wore a custom Gieves & Hawkes suit. Images of the wedding will be featured in Martha Stewart Weddings' September issue." Not just romantic -- also profitable!

Saporta proposed to Fetherston six months ago and had the designer's help in picking and designing her ring with jeweler Lorraine Schwartz.

"I'm no dumb-dumb. I know you don't buy jewelry for a girl without consulting her -- especially for a girl like Erin," Saporta said. "[Erin] gave us creative direction, and I worked with Lorraine to make it happen."

"What I really love about Erin is that being with her inspires me to be better," Saporta gushed of his bride. "Erin and I are able to propel one another forward without ever being critical or judgmental. I feel like she sees my shortcomings, she sees my potential, and she's got my back no matter what. She's my teammate and my best friend. There is no one I'd rather spend my time with."
