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!
