Famous Australian feminist Germaine Greer quit Britain's "Celebrity Big Brother" show Tuesday, just five days after joining the reality broadcast.

Greer, 65, declined to explain why.

"I'm leaving over specific issues, but best for everyone if I don't discuss them," the "Female Eunuch" author told the Mirror. "I have a problem with decisions; I make them fast and when I make them, I stick to them."

Her departure follows the surprise arrival of Jackie Stallone, Sylvester Stallone's mother, who is known for her bad relations with another show participant, Brigitte Nielsen, once married to the famous "Rambo" actor, the Sun reported.

Housemates make nominations Wednesday for the first evictions, set for Friday.
