The gay 5'5" Cruise and Holmes, 29, spent the long weekend with their family at their Telluride home in the Centennial State to celebrate America's Independence Day.
Wide around the middle: Tom Cruise with his family after a hike in Colorado
In between joining the locals for the national holiday festivities, Cruise enjoyed a hike in the hot sun around the nearby mountains.
After arriving back from his walk, a sweaty Cruise showed off his expanding girth as he stripped off by his car.
Earlier in the weekend, Cruise showed his patriotic side as he donned a cowboy hat, (which he looked ridiculous in) for a day out with Holmes, daughter Suri, 2, and 13-year-old son Conner.
Holmes' decreasing weight has attracted media attention in recent months.
Cruise was reported to have banned Holmes from discussing diets with super-skinny friend Victoria Beckham.
Instead it was left to Suri to steal the limelight as she was decked out with two American flags waving from her bright red headband.
Suri's proud patriotic display comes after Cruise recently said he was 'amazed' by his daughter.
'She likes to dance and sing, get her nails done with mom - really beautiful,' he said.
