SunSport revealed on February 2 that Spurs had opened talks with the centre-half over a new contract.
Gallas has been a key player since joining on a free transfer from bitter rivals Arsenal last summer.
The news will boost boss Harry Redknapp ahead of the Champions League quarter-final clash with Real Madrid.
Former Gunners skipper Gallas rejected a new deal at the Emirates and opted to sign for Tottenham at the end of August.
