Orange Is the New Black star Laverne Cox, who plays transgender inmate Sophia on the Netflix series, received a holiday card from Beyonce this week. Cox posted a photo of the card on Instagram Friday, and revealed that she essentially freaked out upon getting it.

"So when I opened this holiday card a few days ago and read Love @beyonce I literally fell to the floor," Cox wrote with the photo. "I was on the floor of my apartment. I have witnesses. Love the #CakeByThePound sweatshirt. Thanks Bey for the gift. I have had an awesome year and this is certainly a highlight. Happy holidays Mrs. Carter to you and your beautiful family. Thanks for all the amazing music and endless inspiration you've given to me and so many over the past 16 years. Since No No No I have been saying YASSS YASSS YASSS! #QueenBey foever."

It is unknown if Beyonce is a fan of Orange Is the New Black. Even if she isn't, Cox has become a hugely influential figure in the transgender community. In August she became the first openly transgender person to be nominated for an Emmy for acting.

Cox and her fellow castmates previously recorded a version of The 12 Days of Christmas for the holidays.

Orange Is the New Black returns for its third season in mid-2015 on Netflix, though the streaming site has not yet announced a specific release date.
