I'm a fan, Amanda's a fan, and even Christina's a fan. Now, we spot Natalie Portman toting her cute pooch across the country in a Sherpa, too! I have this very model of the popular brand because of its special flap features: You can roll and snap up the sides to let a pet breathe the fresh air, but then pull down the shades for some shut-eye on the plane.

It's also a practical purchase from the price standpoint as well – the Sherpa Roll-Up normally retails for $85 and up but I did a quick search to see what deals I could sniff out. Lo and behold I found the small size for just $55, the medium one for $76, and the largest version for $88. Will you set sail with this celebrity pet trend or does your furball already have a Sherpa in stock?
