Showing off her newly remodeled figure, Heidi Montag was busy flaunting her bikini body in Las Vegas, Nevada on Saturday afternoon (April 10).

In related news, Miss Montag and husband Spencer Pratt took time a few days prior visiting Marine Corps facility Camp Pendleton in San Diego County.

The "Hills" hottie posed for pictures at Aria at CityCenter before removing her beach cover as she grabbed up a lounge chair at the popular Sin City destination, Liquid Pool.

Telling of the trip, Heidi and Spencer told People magazine, "We went to visit Camp Pendleton to see the Marines. They’re the most valiant, honorable and courageous men and women in the United States. It was one of the best days of our lives."

The MTV reality star couple adds, "Our freedom is so important to us and thanks to these Marines we get to be the entertainers we are. We wanted to take the time to honor them and pay our respects to the Marines who make this country and nation possible and allow us all the freedoms that we enjoy."
