Jamie Alexander has said she is recovering in hospital after her appendix ruptured.

The Blindspot star shared a photograph of herself in a hospital bed with a tube going into her arm but still encouraged fans to watch the latest episode of her hit show.

She wrote: โ€œHey guys! Appendix ruptured but am on the mend! Just wanted to say a quick hello and let you all know that one of my favorite episodes is TONIGHT!

โ€œIโ€™m so excited for you all to see it @TheVulcanSalute is phenomenal #blindspot 8/7c TONIGHT on #NBC.โ€

Days earlier Alexander tweeted a photograph of herself drinking herbal tea in a hospital bed, bearing the words: โ€œCheers to my appendix.โ€

The actress, best known for her role of Sif in the first two Thor films, has played a woman found in Times Square with no memory and mysterious tattoos on her body in Blindspot since 2015.
