First topic message reminder :Basically what the title and description say, talk about what people in real life look similar to in the Winx Club show. Doesn't matter if it's a younger, older or present version of the character. And it's your opinion, so don't feel like it's wrong.
For me...
Felicia Day looks a lot like Bloom
Hayden Panettiere looks like Stella
Britney Spears resembles Icy
Megan Fox resembles Darcy
Lady Gaga then resembles Stormy (results may vary)
Of course, these are all my opinions, but I really need to expand on my knowledge of female celebrities.
