Furious Dancing On Ice bosses have reportedly threatened to axe any contestants who stay out drinking after midnight on Sundays.
The Sun reports that the skating celebrities and their partners have visited a hotel near the studios after the live shows each week, and have been known to stay up until 5am drinking, just five hours before rehearsals begin.
As a result, producers have introduced the curfew - and anyone who turns up to training under the influence will apparently find themselves in danger.
An insider told the newspaper: "If they don't obey the rules they could be skating off earlier than they thought."
Charlene Tilton became the fifth star to be voted off the show last night.
