The professional dancer's relationship with show bosses is said to have soured over the past year, since her husband James Jordan was axed from the show, reported Daily Mirror.
Jordan has grown sick of tensions with bosses and will leave at the end of the current series.
Jordan and her celebrity partner sprinter Iwan Thomas were the first couple to be booted off the show this series, after an underwhelming cha-cha routine.
"This has been on the cards a while. She's very loyal to James so when he was forced out it left a sour taste," a source said.
Jordan first joined the show in 2006 and is its longest-serving female professional dancer. In 2009 she won the competition with celebrity partner, broadcaster Chris Hollins. She has been married to fellow pro dancer James Jordan since 2003.
