What secret do these five Hollywood Stars share?

You can bet it's something they don't want you to know about. Well, at least until after they're long gone!

But ... Celebrities love Philipsburg, Montana!

Colin Farrell joined the ranks of the A-list of visitors who frequent the area last week. During his stay he stopped in at local businesses such as The White Front Bar and Doe Brothers.

Montana's hottest small-town tourist destination has put it on the map as a must-stay for some of the entertainment world's elite, bunking down at the ultra-exclusive The Ranch At Rock Creek. Recent guests have also included country superstars Carrie Underwood and Leanne Rimes. The latter is a regular and known for singing campfire songs with other guests.

In recent years, both Kate Bosworth and Scarlett Johansson have had their weddings at The Ranch, located just outside of Philipsburg. Johansson married her husband Romain Dauric in the fall of 2014. Bosworth married American director Michael Polish there in 2013.

Last summer Gwen Stefani visited The Ranch right before her relationship with Blake Shelton was made public. It was not confirmed whether or not he was with her during her stay.

The guest list at The Ranch is top secret and employees are not allowed to make any sightings known.

The Ranch At Rock Creek is a Montana hot spot for the stars. On its website, The Ranch states that it's, ”The world’s only Forbes Travel Guide five-star guest ranch”. And according to Yahoo Travel/Hotels, "Designer Jet Zarkadas has created an atmosphere that feels super-chic yet country comfy."

Another reason to love the charm of Philipsburg, Montana. You just never know who you might run into downtown!
