Turns out we were right after all … we think.

Spencer Pratt and Heidi Montag looked like anything but a couple on the brink of a February divorce when they were spotted recently celebrating Heidi’s 24th birthday. The couple was also recently stopped traveling (together) back to the States from Costa Rica. Now, new

rumors about their trip outside the country have been unearthed, and there’s strong reason to suspect the entire breakup was a publicity stunt … which is just so Speidi.

A source says the couple shared a house together for most of the summer, making extensive changes to the property while they were there. Trees were planted along the front of house to provide privacy, the pool water was changed from chlorine to salt water…they even fired the gardener. The couple announced their break up in May. Heidi Montag officially filed for divorce in July.
