Looks like it is a bad week for octogenarian love.

First 85-year-old Hugh Hefner loses his fiancée and now PEOPLE is reporting that 81-year old Buzz Aldrin has filed for divorce from his wife of more than 23 years.

The astronaut and former "Dancing with the Stars" contestant reportedly separated from his wife on Tuesday and is citing "irreconcilable difference" in the divorce petition filed Wednesday in Los Angeles County Superior Court.

Lois Driggs Cannon was Aldrin's third wife and could often be seen cheering him from the audience when he competed last year on "DWTS."
