It’s like a game of spot the difference. Kate Beckinsale and Kate Middleton may have the same first name and they are both British but, believe it or not, they are two very different people. So when a news outlet mistakenly mixed up the two in an article earlier this week, the 45-year-old actress took to social media to poke fun at the awkward error.

On Wednesday, January 30, Kate took to Instagram to share a screenshot of a headline about her recent hospital stay after she suffered a ruptured ovarian cyst. And it seemed like a normal post until we (and she) realized the photo that accompanied the article was not of the Underworld star at all, but instead, it was of the Duchess of Cambridge, 37.

“So moved and touched by all the kind wishes I have received over the last few days and staggered by the similar and worse stories my #cysters have been sending me,” she captioned the photo. “I am feeling much better and I hope all the other girls going through it are too.” The former TV actress then decided to wrap things up with this hilarious add: “Back to resume my royal duties. William says hi.”

It was just a few days ago that the non-royal Kate told her fans and followers that she was in quite the bit of pain due to the ruptured cyst. “Morphine makes me cry,” she captioned a photo of herself with teary eyes while in a hospital room. The mother-of-one then revealed the reason she decided to let everyone know about her scary health situation.

“I would not have posted it if we had not noticed someone in a car taking a photo of me leaving the hospital in a wheelchair,” she explained. “I have Instagram largely to have my own honest narrative and not have to always be ambushed by stories that come out that are invented. I’d prefer to say what happened than endure speculation and so I chose to share. I agree it’s not a normal impulse [to post a hospital photo]. But it’s not normal to be photographed in vulnerable situations by people you don’t know either.”

Well, we’re just glad Kate is feeling better and is now, apparently, part of the royal family.
