Gina Schulman, a spokeswoman for the star of Nickelodeon's "iCarly," says the accident happened early Thursday on Interstate 70 near Vandalia, 70 miles northeast of St. Louis. Schulman says all five passengers on the bus "will be fine."
Schulman says Cosgrove's "Dancing Crazy Summer Tour" is postponed until further notice. Cosgrove was scheduled to perform Friday in Wichita, Kan., and Saturday in Denver.
She says, "Miranda thanks everyone for their understanding and support."
Cosgrove stars as Carly Shay, the daughter of a colonel serving overseas, on "iCarly." Her album is "High Maintenance." She also featured in "The School of Rock" and voiced the character Margo in "Despicable Me."
