The Coast Guard says singer Kelly Rowland was among the passengers on a private boat escorted back to Cape Cod after the captain became disoriented.
Lt Ruairi White told the Cape Cod Times that the boat's captain was following a commercial whale-watching vessel, lost sight of the boat and became disoriented north of Provincetown.
The Coast Guard directed a commercial towboat operator to escort the private vessel back to Provincetown.
TowBoat US Provincetown said on its Facebook page that the boat was 53 kilometres north of Provincetown.
It said the passengers "were great. Just a little shook up."
Rowland is a founding member of Destiny's Child, where Beyonce launched her career.
The group briefly reunited this year when Rowland and Michelle Williams joined Beyonce for a Super Bowl performance.
