Let's set the record straight. They're not engaged, but they're going strong.
The Black Eyed Peas front-woman / hit solo artist and the Las Vegas star / Johnny Knoxville look-alike say the secret to a happy relationship is...
Fishing, cooking and karaoke.
"We always do quirky romantic things," Fergie told People. "It's not just Valentine's Day. Like we went to Cabo San Lucas, and we took a cooking class and we went fishing for marlin and mahi mahi. We sing karaoke. At Josh's house, he has a karaoke machine."
Apparently, Josh Duhamel isn't half bad.
"Sometimes we'll sing really corny duets together when a couple of our friends are over," says the "London Bridge" singer of her man.
"He does 'Total Eclipse of the Heart,' which is amazing. You've never seen anything like it. He gets into it. He's pretty good. He's better than you would think!"
Duhamel, who is about to wrap the fourth season of Las Vegas, said they're figuring out how to avoid the pitfalls of a high-profile relationship (listen up, Britney Spears).
"We just genuinely love each other," he said. "We stay out of the spotlight as much as we can. So many times people are too in the spotlight, which puts too much pressure on things."
That doesn't mean they don't pay attention to what the media is saying about them. Last week, Fergie denied reports - again - that she and Josh are getting married.
"We get a kick out of it," Fergie told People. "Every other week, we hear we're engaged."
At the 5th Annual Cadillac Super Bowl Grand Prix, where stars raced go-karts for charity, Duhamel, last year's defending champion, was excited about taking on Fergie, who was racing for the first time.
"I'm looking forward to beating my girlfriend," he said. "She's been talking smack all week. She wants a trophy of her own."
"I'm just hoping my natural abilities will come into fruition during the race," Fergie joked. "We get a little competitive sometimes. We had a lasagna cook-off one time and basically I was the better bluffer. He won the contest because mine ended up soggy."
Unfortunately for the "Fergalicious" singer, she was defeated in the first round of the three-round race, which also included Nick Lachey, Queen Latifah, Paul Rudd, Terrence Howard, Venus Williams, Melina Kanakaredes and Matt Leinart.
Lachey, who finished second was there without his girlfriend, Vanessa Minnillo.
"She bailed on me," he joked. "She doesn't want to see me get thrown into a bail of hay."
