Heidi & Spencer's Honeymoon -- FIRST PICS!

Here are the first pictures of The Hills newlyweds Heidi Montag and Spencer Pratt soaking up the sun on their Mexican honeymoon. Another hilarious photo shoot to add to the books!

The happy couple, who eloped south of the border last week, was seen enjoying their first week of wedded bliss at their private villa in the exclusive One and Only Palmilia resort in Los Cabos. While there, Speidi was also seen filming scenes for an upcoming episode of The Hills.

Earlier today,Spencer called Ryan Seacrest‘s radio show Thursday to respond to comments made by Heidi Montag‘s mom.

Spencer fired back, saying, “I can’t wait to prove her wrong and be married for the rest of our lives. I’m sure she’s just hurt and reacting crazy because she wasn’t there.”

When asked if he’ll be spending the holidays with Heidi‘s mom, Spencer said, “The Pratts – as in Heidi Pratt and Spencer Pratt – will probably have their own Christmas tree.”
