Kaley Cuoco and Zosia Mamet now have a permanent reminder of their time filming The Flight Attendant together.

The two actresses shared photos on Instagram getting matching tattoos to commemorate their friendship and the show, which is set to premiere on HBO Max later this year.

"A special little tribute to our wonderful little show .. ✈️ " Cuoco, 34, wrote in the caption for a series of photos.

In one snapshot, she and Mamet, 32, smile as New York tattoo artist Evan Kim bends over the Girls star's ankle.

The duo received a line tattoo of a paper plane with a trail, a nod to the drama's title. Cuoco tagged costume designers Catherine Marie Thomas and Olivia Janczyk, as well as Catherine Horton, who also got the same tattoo.

In an Instagram post of her own, Mamet wrote, "after a full year and many adventures together we decided to get a little memento. Thank you @evantattoo 💛#theflightattendant ✈️✨"

Last month, Cuoco shared a black-and-white selfie with Mamet on Instagram, giving fans a glimpse into how production on The Flight Attendant was going during the novel coronavirus (COVID-19) pandemic.

This experience was magical. During a time in our world that is quite dark this was a real light for me. I hope all of you out there are finding your light too. 💛 @kaleycuoco I love you.

While The Flight Attendant does not yet have a premiere date, Cuoco said in August that it might make its debut in November.
