Josh Duhamel

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."

For a time, she was hooked on crystal meth. Now, she's simply addicted to love - and possibly willing to commit to her man forever.

But Stacy Ferguson, better known as Fergie, is trying to keep her engagement a secret by hiding her ring in her handbag when she's out in public.

That's according to recent tabloid reports, which say the Black Eyed Peas singer and current solo artist accepted boyfriend Josh Duhamel's marriage proposal just before Christmas, but doesn't want to make the news public until they have set a wedding date.

Life & Style magazine claims Fergie Ferg was showing off a four-carat diamond engagement ring at a pre-Christmas party at film producer Michael Bay's home on December 15 - but has kept it hidden ever since.

This isn't quite up there with the engagement rumors swirling around Paris Hilton and Stavros Niarchos, but it's still the subject of tabloid fascination.

Duhamel's representatives have denied the engagement news, but a friend of the couple tells Life & Style magazine that she can't wait for her London Bridge to go down... or something:

"They don't want to announce the engagement until they set a wedding date, but Fergie can't wait to marry Josh."

Sources suggest the couple is considering a European wedding next summer. An insider says, "She wants a big, formal wedding."

How appropriate for a woman calling herself The Duchess.

And really, who wouldn't want to marry Josh Duhamel. If you're unfamiliar with this gentleman, he's probably best known for the following things:

• Starring on NBC's hit series Las Vegas
• Looking a lot like Jackass star Johnny Knoxville
• Not bringing much to the table in terms of acting talent
• Being hot enough to inspire a man-crush from a straight guy

At T.H. Gossip, thinking up Celebrity Look-Alikes is one of our favorite pastimes. Another is thinking of new synonyms for "slut" when writing blogs about the luscious Lindsay Lohan, a.k.a., The Hollywood Harlot.

But we're here once again to talk about the former. Our dead-ringer pairs run the gamut from the virtually indistinguishable (Will Ferrell and Chad Smith) to the eerily similar (Suri Cruise and Bjork) to the absurdly inaccurate, yet still funny (Tom Cruise and Kim Jong Il).

This one falls into the first of those three categories. If Las Vegas star Josh Duhamel (right), appeared on Jackass as a body double for the insane stuntman and actor, Johnny Knoxville, would anyone be the wiser? At least before his group of rowdies poured hot sauce down his pants or pushed him off a pier in a shopping cart?
