One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
The real designer behind the gown is Michael Angel and needless to say he's pretty peeved about not getting credit since he "designed the dress specifically for Gwen".
To add insult to injury, Angel's creation was auctioned off that night and billed as "a creation of her own, by L.A.M.B.".
At the end of the night not Gwen's dress sold for $125,000 with the proceeds benefiting AIDS research. So really, he shouldn't be THAT mad about this whole situation. That's a lot of money going to a great cause!
