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!

Heidi Montag is hoping to prove she's still a celebrity by making an appearance at Hard Rock Hotel & Casino in Las Vegas to celebrate her 25th birthday.

The reality star, along with her hubby Spencer Pratt, partied at 35 Steaks + Martinis. We're told the birthday girl ordered Colorado lamb and lobster tail. Sounds delish.

A source from inside the club says partygoers celebrated her big day with a round of "Heidi fun shots" and, of course, champagne.

After dinner, Heidi and her crew headed to Vanity Nightclub where we're told the drinks continued flowing. The former Hills star also received a red velvet cake in the shape of presents.

Judging by her expression, we can tell it was a good night!

Heidi Montag loves fame, and everything it has to offer -- until now.

A year since The Hills' finale, the cosmetically-enhanced blonde has stayed out of the spotlight. And my, how fast time flies!

Heidi is putting herself right back in it by starring on the new reality show, On Reality Food, alongside ex-Bachelor, Jake Pavelka, and ex-Real Housewife of New Jersey, Danielle Straub.

We caught up her Wednesday evening at the opening of new a restaurant, Lemon Basket, in West Hollywood, along with some other celebs (click through to see who else showed up).

Heidi recently told reporters about her desire to maintain her privacy being back in Hollywood:

"From now on, I'm going to keep my life a little more private ... I enjoy my privacy. I'm just kind of getting my feet back into Hollywood."

For future reference, Ms. Montag, if you enjoy your privacy, don't do a reality show!
