Justin Bieber’s North American tour isn’t the only reason he has his hands full these days. The singer has a new tour buddy that fits in his palm.

Bieber introduced his new friend, a hamster named Pac, on Oct. 20, and has had fun sharing photos of the tiny rodent ever since.

“This is PAC the hamster my new believe tour pet I will bring him to every meet n greet,” he Tweeted with a photo of his furry friend in a cage.

He held the brown hamster at an event with music video director Alfredo Flores on Oct. 27 and a few days later the star shared an Instagram shot of Pac sitting calmly in his palm.

“Me and #pac on the road,” he wrote.
