“Every time we got a rewrite in the script, there would be more making out!

I would just go, ‘Oh my god.

I just gotta close my eyes and do it.

she says, laughing again.

I’m so fine with this."

“Kitty Forman, making out with the child!”

“They needed somebody who could make it believable,” she says.

“Apparently I had no problem with it whatsoever and made it entirely believable.”

“There was no socializing.

There was no chit-chat there,” she says.

“They weren’t like mean or dismissive or condescending at all.

That might have colored things a little bit.

I don’t know how it could not.

[But] they were very professional.”

“Because that was my character!

It was completely appropriate.”

Phoebe agrees to be their surrogate and ends up giving birth to triplets.

“I knew the show.

I loved the show.

I thought it was really funny,” Rupp says.

And when her oneFriendsappearance turned into a six-episode arc, Rupp was overjoyed.

And she also owes a huge personal debt of gratitude to herFriendsscene-partner Kudrow.

“Around this time, my mother was diagnosed with a very fast-moving Parkinson’s,” Rupp says.

Basically, they kept my mom alive.

It was just pretty amazing.

Lisa did it because Lisa is just who Lisa isjust a kind person."

And now thatFriendsis celebrating its 25th anniversary"I had a heart attack when I read that.

Why am I not dead yet?"

Rupp says with a laughshe’s finally ready to air what she considers to be an embarrassing secret.

“They had this big, huge party and I got Brad Pitt’s autograph.

I was like the geekiest, stupidest fan.”

“I don’t get recognized, it’s my voice that gets recognized,” she says wryly.

That laugh is just freaking obnoxious and I got stuck with it."

She pauses, then adds seriously, “I’m very careful now with how I laugh.”
