Green was recently quoted as saying that the public must have been "on acid" when they voted for the pair, adding: "It put its paws on her arse and moved around, and the f**king country goes crazy... I've had dogs that can do better f**king s**t than that."
Speaking to Digital Spy, Butler said that although she respects Greene's opinion of her and Pudsey's act, his comments were still difficult to take.
"You know, it wasn't the nicest thing in the world, but I suppose he has his own opinion," the teenage star said. "It wasn't the nicest way to read it in that article what he thought.
"I didn't think he expressed [himself well]... but if that's what he thinks, that's what he thinks."
Butler added that she is "so busy" that she has yet to spend much of her £500,000 Britain's Got Talent winnings.
"I think the only thing I've been buying at the moment is clothes because I need so many of them," she claimed.
"I did give [Pudsey] £250,000, but he's a dog and he won't know what to do with it, so I'll just have to spend it for him."
Ashleigh & Pudsey are to appear in Woking's Dick Whittington pantomime, which will run at the New Victoria Theatre from December 7, 2012 to January 6, 2013.
