Katherine Heigl may have been the celebrity guest on The Tonight Show Tuesday, but it was the actress who walked away star-struck.

During an appearance to promote her new movie New Year’s Eve and her recently-launched neutering campaign, I Hate Balls, Heigl scored some one-on-one time with pool-playing pooch Amadeus.

“How cute is that little dog?” she says in a backstage video where she cuddles the Chihuahua and chats with owner Connie Baldwin. “He’s so sweet!”
