The 18-year-old was given a picture of her boyfriend's new waxwork as well as a picture of him in real life and she easily picked out her man.
She said to Access Hollywood: 'Oh, come on! They did that last year and he's grown a lot since then. Come on! That was last year they did that. I know my real one.'
The star added that she will be sad to leave her Disney show The Wizards of Waverly Place later this year.
She said: 'I'm extremely sad that the show's ending, I'm definitely sad. But I do think it's time. It's like high school - you kind of feel like there's a point where you want to go on to the next chapter, so I'm very excited.'
