Sean Kingston has been accused of attacking a woman during his supporting act stint on Justin Bieber’s 2010 tour.

After landing at LAX on a flight from Miami earlier this week, 22-year-old Kingston was officially served, according to reports from Radar Online:

Beautiful Girls singer Sean Kingston has been served with a civil summons and complaint in connection with a lawsuit to be filed alleging he was involved in the gang attack of a woman. Kingston…was served Friday night with the legal docs, linked to an incident that allegedly occurred after a concert in 2010 in which Kingston opened for the Baby singer.

The private investigator who officially served the legal documents told Radar reporters he had no comment and was at LAX on official business.

There has been no official word released from the Kingston camp as of yet.

Kind of hard to believe a big ol’ teddy bear like Sean Kingston could ever lay hands on a woman, don’t you think?
