Hoolahan wanted to move to Villa in January and his reaction to his goal upset some supporters.
"Having spoken to him I am very clear and very confident that there was nothing in that or in the way he reacted after scoring," said Hughton. "This is a lad who has had a tough time this season in terms of the number of games he would like to have played.
"He is an experienced player who is used to playing but he has had to get used to that and maybe when you have not played for a period when you do score you forget how to celebrate.
"I am genuine in what I say that if he has upset anybody or taken that reaction the wrong way Wes would be the first one to apologise or hold his hand up.
"What he did do, and I feel it is important to recognise the fact, is I saw him go over to our support at the end to show his appreciation. I am very clear about what he has told me and I feel it is genuine."
