Spencer Pratt is currently locked up in the Celebrity Big Brother house, but fans are speculating that the reality star's phone may have been hacked or stolen, as his Twitter account is still very much active. Or um, maybe Spencer's been tweeting all along?

He wrote, "Listen, tweeps, keep calm and carry on. This is perfectly explainable. I have been allowed to tweet as a plot device in the season," and later added, "Surely, the tabloids would have a field day with the contents of my phone, their cup o' tea.... Thanks for the concern. No hacking here. Actually it's good I found my phone. Contacts, pictures, all sorts of things some1 might want."

Additionally, the above photo of Heidi was posted to the account, and he wrote, "Some have suggested that this is NOT my phone. To them, I share one of the many photos of my lovely wife Heidi."

Now here's a name we haven't heard in a while!

The Hills star Heidi Montag is set to host the third anniversary bash for Las Vegas gentleman's club Crazy Horse on Oct. 19 for a whopping $25,000 appearance fee!

"I am so excited to host Crazy Horse III's third anniversary celebration. I'm ready to party!" Montag said in the press release.

The blonde bombshell will not be stripping down for the soiree, as she is only on hand appear. Husband Spencer Pratt will take time out of his busy schedule as a USC political science student to accompany his wife to the gig.

Not that Miss Montag hasn't been asked to show off her assets for a price in Sin City, though! Back in 2009, the 26-year-old was offered $25,000 to dance five nights a week at Scores Gentlemen's Club, which she turned down.

Speidi is back and up to their old tricks... making money doing essentially nothing!

We haven't seen these two in a while! Not to jump to conclusions, but are they promoting something?

Heidi and Spencer Pratt were snapped leaving dinner at Il Cielo in Beverly Hills last night, and even though the former Hills starlet has enhanced her looks quite a bit over the years, she kept it simple with jeans and minimal makeup.

Spencer tweeted, "Had the most romantic dinner with @heidimontag last night!" Can you believe these two have been married for over three years now? That's like an eternity in Hollywood!

Heidi Montag and her store-bought cleavage are both back on the scene!

The 25-year-old blonde reality show star is showing off the cover art for her upcoming EP, "Dreams Come True."

Heidi's first album Superficial, which was released back in 2010, sold less than 1,000 copies during its first week of release. Yikes!

Let's hope the surgically enhanced singer has better luck this time around!

We have a feeling that hubby Spencer Pratt will be at the stores to buy the first copy ... and yep, he'll probably make sure it's a photo-op!

Heidi Montag and Spencer Pratt aren't quite the couple they used to be!

The Hills star stepped out with a bloated, puffy face -- did she get more plastic surgery as a V-Day gift? While her overweight hubby was sporting a very un-sexy pot belly in Malibu, on Tuesday afternoon.

Looks like those Vegas pool party days are over!

It's been reported that Heidi and Spencer went bankrupt after her 39 plastic surgery procedures and the couple's lavish spending, but one thing's for sure -- they're still very much together!

Montag Tweeted on Tuesday, "Getting ready for Valentines day! This will be my fifth one with the love of my life, my hubby, @spencerpratt!"

After five years as "Speidi," they're still going strong!

Heidi Montag has taken a break from the media spotlight, and looks like it's done her a world of good.

The former reality star looked easy, breezy and (yep, dare we say) beautiful while heading to lunch in Santa Monica. We kind of love the irony of Converse Chuck Taylor Shoes ... and a Chanel wallet. Oh, Heidi.

Spencer Pratt's wifey is reportedly writing a tell-all memoir, so perhaps she's been staying indoors .... working on this project. Question is, do we care what she has to say about her made-for-TV life?

For her sake, we hope someone does.

Looking ultra casual in matching low-key ensembles, Heidi Montag and Spencer Pratt enjoyed a romantic day together in Malibu, where they did a bit of shopping before relaxing on the beach.

While it seems reality TV's most unpopular couple has been avoiding the spotlight lately, they're actually hard at work on more serious projects!

Montag has been busy writing a "tell all" book, while Pratt has re-enrolled at the University of Southern California to finally complete his degree.

They've emerged!

Heidi Montag and Spencer Pratt happily disappeared from the limelight after Heidi's many plastic surgeries, but the two were spotted by X17 photogs Monday afternoon.

The Hills stars tried to keep a low profile as they ran errands in Malibu, but we did notice one fishy thing -- Heidi kept trying to cover her stomach with her giant Louis Vuitton purse. Could she be hiding a baby bump?

It wouldn't be great timing for the two, considering that Spencer appears to be broke. Us Magazine is reporting that he calls his agents 30 times a day, but all they do is laugh and hang up on him. He also owes his agency "hundreds of thousands of dollars in commissions" from his earnings on the MTV reality series, according to the same source.

But Heidi has publicly made it clear that she's sticking by her hubby's side under any circumstance. "Thank you @spencerpratt for marrying me! I love you!" she Tweeted last week.

Aw, reality TV love!
