Actor and entrepreneur Blake Lively apologizes about her joke on Princess of Wales Kate Middleton’s Photoshop fails with the apology coming after Princess Kate confirmed on Friday that she had undergone treatment for cancer.

“I’m sure no one cares today, but I feel like I have to acknowledge this,” Lively said in a message shared Friday on her Instagram account. “I made a silly post around the “Photoshop fails” frenzy, and oh man, that post has me mortified today. I’m sorry. I am sending love and well wishes to all, always.

Last week, the New York Post reported that the Gossip Girl actress shared an edited photo to promote her beverage company, Betty Buzz, which featured an abnormally large thumb and a floating lemon. In the since-deleted Instagram post, Lively wrote,

“I’m so excited to share this new photo I just took today to announce our four new @bettybuzz & @bettybooze products! Now you know why I’ve been MIA.”

According to the outlet, the photo was a reference to visual anomalies in a photo released Mar 10, which Princess Kate released amid conspiracy theories about her whereabouts after undergoing planned abdominal surgery in January.

However, the photograph sparked speculations about why the princess had been keeping a low profile most of this year. The princess apologized for any confusion caused by the image and revealed that she had digitally edited it herself.

“Like many amateur photographers, I occasionally experiment with editing,” Kate said.

In a video statement released Friday, Princess Kate said her cancer diagnosis was discovered following abdominal surgery, and she is now in the early stages of preventative chemotherapy.

“It has been an adamant couple of months for our entire family, but I’ve had a fantastic medical team who have taken great care of me, for which I am so grateful,” she said in the video.

Following the news, King Charles III released a statement. A Buckingham Palace spokesperson told the outlet that the monarch is so proud of Catherine for her courage in speaking as she did.
