Annnnnd some eye-witnesses said the whole fight started because LiLo was jealous that Max was chatting up another chick (a.k.a the "psychic").
Max from "The Wanted" -- ya know that guy Lindsay Lohan wants to bang -- is officially on TEAM LILO ... because he just told our camera guy (with a straight face) ... "Lindsay's a good girl."
Max (and his boy band) were at LAX yesterday -- and we asked him all about LiLo's problems ... considering he partied with Linds the night she got arrested for allegedly punching that psychic in the face.
Surprisingly, Max gave LiLo a glowing review ... specifically saying, "She's fine. She's out of trouble ... Lindsay's a good girl."
So we gotta ask ...
