The argument originally started when Fergie approached Perez asking him why he was slamming the Black Eyed Peas new album, and it escalated from there.
Fergie has an army of supporters and fans, including her mother Terri Jackson, who are standing by her side and are even convinced Fergie "could have taken him down."
Fergie's mother talked to Hollyscoop at the Transformers: Revenge of the Fallen movie premiere in Los Angeles Monday night about the feud and what they really think about Perez.
"Thank God it wasn’t Fergie," Terri told Hollyscoop, "I think she could have taken him out," she joked.
When asked what she thought about Perez and his comments about celebrities, Fergie's sister Dana Ferguson told us, "Perez always seems to have his opinion on everything and it seems to clash with a lot of people, and I think he does that on purpose sometimes and sometimes he's gonna get some backlash."
Fergie's father Pat Ferguson was so upset with him he told us, "You don’t want my opinion on Perez Hilton!"
While Fergie was MIA due to work obligations, her family came out to support their son-in-law Josh Duhamel, who stars in the movie.
Sorry Perez, but it looks like the world is siding with Will.i.am and the Black Eyed Peas on this one. Even GLAAD is upset with Perez for the comments he made during the argument. Whose side are you on? Check out our exclusive interview below.
