In the new Netflix comedy Grace and Frankie, Lily Tomlin and Jane Fonda star as two women who “form an unlikely bond after their husbands reveal they are gay and leave them for each other.”

The show is called Grace and Frankie, and Tomlin & Fonda are its main stars. But apparently, the show’s male actors (Sam Waterston and Martin sheen) are getting paid just as much as they are – and this doesn’t exactly sit well with either.

Speaking at a press event before the premiere of the show, Fonda and Tomlin sounded off about a hot button issue as of late – the gender pay gap.

“Lily found out Sam and Martin are getting the same salary that we are,” said Fonda. “That doesn’t make us happy.”

“No. The show is not Sol and Robert — it’s Grace and Frankie,” said Tomlin.

Both Tomlin and Fonda clearly feel as though they should be earning more than their male counterparts, since they are the main focus of the show.

Charlize Theron recently negotiated a deal to be paid as much as her Snow White and the Huntsman co-star Chris Hemsworth.

“‘I have to give them credit because once I asked, they said yes,” she says. “They did not fight it. And maybe that’s the message: That we just need to put our foot down. This is a good time for us to bring this to a place of fairness, and girls need to know that being a feminist is a good thing. It doesn’t mean that you hate men. It means equal rights. If you’re doing the same job, you should be compensated and treated in the same way,” she said.

And Jennifer Lawrence also reportedly won a fight to be paid more for an upcoming film.

All 13 episodes of Grace and Frankie are now available to stream on Netflix. So far, the show has received mixed reviews.
