All seems patched up now between Johnston and Palin, both of whom have dabbled in reality TV and are married to other people.
"The good news is that it appears the custody situation is settled," Johnston wrote on a GoFundMe page in a plea from him and his wife, Sunny, that has generated US$10,225 in its first two days.
"The bad news is that we still owe many thousands of dollars in legal fees."

"Unlike some we are not able to raise money through fundraising e-mails or SuperPACS and are instead asking for your help in paying these bills and allowing us to get back to the important job of raising our family."
