Miley Cyrus was fired from Hotel Transylvania for a birthday prank she played on then-boyfriend Liam Hemsworth when she was 18.

The "Flowers" icon opened up about the experience on the June 10 episode of Reclaiming with Monica Lewinsky, revealing that she was replaced with Selena Gomez because the producers considered the joke "inappropriate."

"As a joke, I got my boyfriend a penis cake for his birthday. And I got fired. I was the lead actress in Hotel Transylvania, and they fired me and replaced me because I had made an inappropriate adult joke. But I was 18! So yes, I was fine to work in a kids' movie, but I [wasn’t] a kid."

Cyrus admitted that she felt "ridiculous" for being fired over the cake but because it's very easy to get them in Nashville for bachelorette parties.

"What felt ridiculous to me about getting fired [for] a penis cake is that they sell penis cakes for all bachelorettes. In Nashville, Tennessee, you can get penis cakes. It’s not that big of a deal. So, I thought, ‘This is a very simple, not vulgar, joke. This is silly, and you can do this for all bachelorette parties’... it felt ridiculous."

The "Malibu" songstress was ultimately let go from the film because of a leaked photo from Hemsworth's party.

"To be fired for regular things that girls my age [do], but at that time, I wasn’t someone that was appropriate for kids, even though that was my personal life. And that photo, again, only revealed itself because the camera had been stolen."

According to Huff Post, Gomez went on to star in three additional Hotel Transylvania films.
