Junior Bradshaw, 30, and Kevin Liverpool, 33, were arrested on Monday after they were seen acting suspiciously around the singer’s country home in south west England.
The police found them in possession of a map and items including a Samurai sword, balaclavas, knives, and a hammer.
Also, handwritten notes were found in a vehicle used by the men which read “rob and kill, money in the safe, Joscelyn rob.” Another note read, “find a river to dump her in.”
Bradshaw and Liverpool appeared in court this morning only to confirm their names, addresses and date of birth.
They were not allowed bail and will remain imprisoned until their next appearance in court on July 1.
