THE breakfast TV ratings battle has turned nasty, with Seven and Nine trading insults over Karl Stefanovic's alleged "drunken" post-Logies appearance on the Today show.

With Sunrise panicked by the much-improved performance of its Channel 9 rival, Today Tonight broadcast an "expose'' of the Today show co-host tonight.

Based on rumours Stefanovic had been taken off air for the past two days as "punishment'' for his appearance and morning-after mumblings on air on Monday, TT aired a package of a giggling Stefanovic.
