Its time to feel young(er) again!

And lets not forget the book editor is still trying to pass as twenty-something at work and beyond.

Being 27 in your forties sounds exhausting, right?

Ahead of the season premiere, we caught up with Foster to get a read on whats to come.

She looked pretty heartbroken in that final scene seeing Josh married.

I think that Josh represents something really important to Liza.

Hes a big part of her rebirth or reinvention.

Hes a huge part of her life.

Its bittersweet and theres real loss and sadness there but shes also hoping hes doing the right thing.

IsJosh doing the right thing?Well…He has a big episode coming up.

Stuff goes down for him in episode 2 with the repercussions of Ireland and realizing what hes done.

The whole world kind of gets flipped upside down.

Are they skipping through the fields happily ever after?

They get some hard moments, but we get some really good moments as well.

I think itll be a really fun summer read.

Its wild for us to see it actually exist and go, My character edited this!

[Laughs] I did a really good job, right?
