Things may have gotten heated between Gretchen Rossi and Vicki Gunvalson on the beach in Mexico on this week's episode of Real Housewives of Orange County, but that scene has actually helped Gretchen in her business endeavors.

Gretchen wore a bikini from her new swimwear line in the episode, and the exposure on the show helped the sexy suit to sell out in the blink of an eye.

"On Monday night's episode, I wore one of the bikinis from my new collaboration with Luxe by Lisa Vogel," Gretchen tells RumorFix.

Gretchen says she got some surprising news when she checked in with the store that's selling her bikini line.

"I'm getting so many tweets [from fans] about, 'Where can I get this swimsuit?' - which you can get at SwimSpot.com or Swim Spot retail stores - and I called [the retailer] today to say, 'Can you send me a picture in the bikini so I can post it?'" Gretchen says.

"And they said, 'Well, we have good news and we have bad news,'" she continues. "'The good news is, Yes, we can send you the picture; the bad news is, we're completely sold out on SwimSpot.com!' And I go, 'Wait, what? It's been two days since the airing!'"

Gretchen says she feels great to know that her product is connecting with so many people.

"It's beyond exciting - I just love that people love my designs enough, and they love what I'm doing for it to sell out that quickly," Gretchen says. "I was really shocked about that one - I've had a lot of my lines sell out, but not that quickly ever, so it's huge."

Congrats, Gretchen! And let's hope the store gets a new shipment in soon!
