Actress Jane Fonda is in negotiations to feature in a sequel to the hit 1980 movie "Nine To Five".

Movie bosses, who are impressed by Fonda's return to the big screen in "Monster-in-Law" - in which she battles Jennifer Lopez over her doted-upon son -, are keen to sign her for a follow-up to the office comedy, reports the Internet Media Database.

Dolly Parton and Lily Tomlin, who had starred alongside Fonda in the film, have been ready and willing to feature in a sequel for some time.

"They've wanted to for years. There's been scripts, potential directors, the works, but everyone thought that for it to really work, they'd need the three leads from the original film," a source said.

"They've talked to Fonda and think they can make this happen. There's some discussion that it might be called 'Nine To Five Thirty'."

Fonda's spokeswoman Pat Kingsley, however, insists nothing has been agreed to.
