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!

Heidi Montag was spotted at Ketchup in West Hollywood Wednesday, and she looks super freaked out!

Wonder what the star was hiding? She was at the Sunset Strip hot spot to film her VH1 reality show Famous Food ... maybe there was a fly in her burger?!

Or, perhaps she's scared of her co-stars. Montag is co-starring on the show with The Real Housewives of New Jersey's Danielle Staub, who got in multiple fights with cast members during her time on that show. Also, Vincent Pastore, former star of The Sopranos, reportedly flipped out on a crew member at the end of filming last night!

Run for your life, Heidi!

See why Heidi's sister was recently in the news -- it's more drama -- after the jump!

Heidi Montag took a few friends shopping yesterday on Robertson -- coincidentally the most visible street in LA and a known hot-spot for celebs (and paps).

Perhaps Ms. Montag is willingly putting herself in front of our cameras ahead of her upcoming reality show for VH1. Publicity anyone???

In the new reality series, Heidi and other reality alums, including The Bachelor's Jake Pavelka and Real Housewives' Danielle Staub, will go into the food biz together and rebuild and re-brand a failing restaurant.

Question -- what does skinny Heidi know about food?

We haven't seen Heidi and Spencer out together in quite a long time!

"Speidi" were dressed down in sweats and hats as they took a trip to the local grocery store to load up their Porsche with some grub. They're just like any other couple -- except for the overblown plastic surgery procedures and constant media attention!

Heidi is gearing up to star in VH1's new series Famous Foods. The show follows reality celebs Danielle Staub of Jersey Housewives, The Bachelor's Jake Pavelka, Vincent Pastore from The Sopranos, singer/mistress Ashley Dupre and Three 6 Mafia members DJ Paul and Juicy "J".

The crew will spend eight weeks working at a new Famous Food restaurant to turn it around and make it a hit. We can't wait to see Heidi work in a restaurant!
