Heidi & Spencer

TMZ has obtained a letter sent by Vivid honcho Steven Hirsch, offering the couple the chance to get behind the lens. The idea, it appears, is to have the gruesome twosome helm skin flicks that will draw directly from the couple's own fantasies.

We're told both sides will get together in the near future and discuss the deal, and Spencer is definitely interested ... if the numbers are right.

With Speidi recently admitting that they're practically dead broke -- a betting website called YouWager.com has offered the couple real life jobs -- with a real big salary -- if they would relocate to Costa Rica.

Here's the deal -- Heidi and Spencer would get a cool $100k to "manage the odds and lines surrounding the entertainment sector ‐- ranging from celebrity news and pop culture to music and movies."

Sources close to Spencer tell TMZ, he's considering the gig -- but in light of the recent political turmoil between CR and Nicaragua ... he's "looking into how he can legally own a firearm over there so that he can protect himself."

As we previously reported, Heidi called off her divorce from Spencer -- and as a symbol of their (unfortunately) undying love, Speidi fed each other s'mores that they'd cooked over an inferno of legal docs.

Heidi tells TMZ she was waiting for Spencer to make her his top priority: "All I ever wanted was to know that Spencer loved me more than he loved all this other nonsense."

For his part, Spencer tells us, "Through everything it's been Heidi's love that kept me grounded. Realizing my behavior was pushing her away was a terrifying wake-up call. I've still got a long way to go to repair the trust, but I hope with continued self improvement, our relationship will be stronger than ever."

The two had been seen out in public together recently -- but yesterday, Montag made the reconciliation official, filing a motion for dismissal at L.A. County Superior Court.

As we previously reported, Montag filed for divorce back in July -- citing irreconcilable differences.

But now, after the two reunited in Costa Rica to deal with a sex tape scandal -- it seems Heidi is once again on board with the whole "'til death do us part" thing.

Spencer tells TMZ he is (finally) going to shave off his scraggly beard. Pratt admits he let himself go when Heidi kicked him to the curb -- but now that they're "spending more time together," she wants him to clean up.

The gruesome twosome just happened to be photographed while kissing on Heidi's 24th birthday in Santa Barbara yesterday -- while Montag proudly displayed her wedding ring.

A rep for the organization tells us, "While Heidi and Spencer did not officially participate in the Avon Walk and were not there in any official capacity, we do appreciate their support of the cause and the event."

Avon also notes that Fergie from the Black Eyed Peas was the official Special Ambassador for the event.

Sources at the race tell us Heidi and Spencer did not walk the course ... but merely showed up for a short while, took photos -- and then left.

As for the couple -- Spencer's rep tells us, "Having lost a mutual friend to Breast Cancer, neither Heidi or Spencer would've missed the event. It's a cause they both care deeply about."

So far, it's unclear if Speidi donated or raised money for the cause.

UPDATE: Sooo ... Spencer contacted us with more details. He claims he and Heidi, "Accidentally happened upon the event, and immediately asked how we could participate. We would've loved to walk, but unfortunately Heidi's surgeries prevented that." Instead, Spencer says they bought "gear" to donate to the cause.

Although Heidi insists she's divorcing Spencer, they were walking in stride in Carpinteria, CA at the Avon Walk for Breast Cancer.

Spencer is fresh off his arrest at the airport in Costa Rica, after he was snagged for illegal firearms possession, cited and released.

As we told you earlier, Pratt told us he was busted in Costa Rica for felony possession of a firearm on his way back to the U.S. yesterday. He was cited and released.

Now, we've gotten our look at an arresting document from Costa Rica -- and even though it's in Spanish, it does have his name on it and includes fun words like "guilty," "charged" and "prosecution" (thank you, Google Translate).

Heidi's name is in there too, listed as his spouse -- and his occupation is listed as "actor."

As the story goes ... Spencer was on his way out of the country when he was busted for felony possession. We're told he was booked and processed at a local jail and later released after turning over the weapons and signing a confession with the DA. Yes, we're skeptical, too.

So far, we haven't been able to confirm any of this. But we do have this bizarre statement from Spencer himself:

"As part of my spiritual cleansing I've spent the last week living alone in the jungle, reflecting on my past transgressions, and working to become a better person. I had to live off the land, and hunt to survive. As I departed the country this morning to continue my spiritual journey, I mistakenly brought my hunting weapons to the airport. It was an honest mistake, and they sent me on my way. On an unrelated note, I'm not allowed in the country anymore -- but that's because of the chicken incident."

Well, we know he can't get arrested in Hollywood ...

Sources directly connected with Spencer tell TMZ ... he wants to move to Costa Rica for two reasons -- it's a lot cheaper than L.A., and he would be closer to Heidi and possibly salvage his marriage.

Of course, reason #2 assumes Heidi is also moving to Costa Rica. So we checked with sources in direct contact with her, and they're now telling us Heidi is indeed noodling on the idea of living in the Republica de Costa Rica.

So the question -- Is this whole divorce thing a pile? Heidi's friends are kinda hedging, saying she loves Spencer but doesn't know how to deal with all the problems.

Karissa's lawyer fired off a letter to Spencer -- claiming that he is in possession of footage that was "taken from [Karissa]" and "contains private materials" featuring herself and boyfriend Sam Jones.
