Going on The Bachelor or The Bachelorette comes with a very specific set of rules for contestants.
Firstly you are not allowed to tell a single person, family or friends, that you have been cast on the show.
Former Bachelor contestant Chelsea Roy previously told Vox: 'We sign a big NDA where we're not allowed to tell anyone that we've been cast and we're going to start filming the show.
'I was able to reach out to a couple of people, local people, and say, 'I would like to support your store in exchange for some exposure in the next few months. Just trust me.'
There are also strict clothing rules. You have to buy all the clothes for the show yourself, even the swanky dresses worn in the iconic rose ceremonies.
Many have spoken out before about how this cost them thousands of dollars.
Like many other reality shows you also have to have a full STI, Covid and psych test before you are given the all clear to start the process.
There is a two-drink rule for the whole process and no music or singing is allowed.
In addition, contestants are filmed 24/7, with many areas (including the mansion) not having air conditioning to ensure clear audio.
In another bizarre rule, contestants aren't actually allowed to eat at all when on dates.
Former contestant Sean Lowe has previously said: 'No one looks good eating, and microphones pick up all kinds of chomping.'
Sean has also revealed that you aren't allowed to use the word 'process' when filming.
He explained: 'Anytime you call it a 'process,' they will make you retape it and say 'journey.'
