Heidi Montag 2010

Here's some pictures of Heidi Montag in Costa Rica on Saturday (she's back in L.A. today). It looks like she had a really fun day at the beach -- especially when her top almost fell off (picture here). I guess that's what she gets for cheaping out and buying a DD bikini from Victoria's Secret. Heidi, silly, that size is for small-breasted women.

The pair - who announced plans to divorce in July, citing "irreconcilable differences" - were reportedly living together in a $5.5 million, rented Malibu beach property throughout the summer months, and had to relocate to Costa Rica after leaving the home in disrepair.



An insider revealed: "Heidi and Spencer made some very expensive upgrades to the house, without the owner's permission. Wanting to keep prying eyes away, they planted 20 foot tall trees along the front of the house against the wall. They also took it upon themselves to change the pool from chlorine to salt water which was very, very expensive. Spencer really loved the house but all of a sudden the owner was notified that they were moving to Costa Rica."



The owner of the lavish property is now said to be working hard to clean up the mess the couple left behind, and even has to rehire a gardener Heidi and Spencer fired.

The source told gossip website RadarOnline.com: "Heidi and Spencer fired the gardener the owner had in place when they moved in. They did so because they have four small dogs and they complained that the gardener was leaving the gate open and letting them out so they brought in their own gardener. The gardener they brought in didn't do as good a job as the previous one and the grounds are having to be brought back to how lush and beautiful they were prior to Heidi and Spencer moving in.



"Heidi and Spencer were required to put down a much bigger security deposit because they have four dogs. The dogs peed on a $15,000 carpet and Heidi and Spencer threw it out without telling the owner."

The pair - who met and married on the set of reality TV show 'The Hills' - sparked reconciliation rumours when they were spotted kissing at Santa Barbara Zoo earlier this week.
