Nicki Minaj announces retirement to start family

Minaj, 36, gave the news to her 20 million Twitter followers, although she had not previously said she was either pregnant or married.

"I've decided to retire & have my family. I know you guys are happy now. To my fans, keep reppin me, do it til da death of me," the singer wrote.

Minaj said in June she planned to marry boyfriend Kenneth "Zoo" Petty, and in August she changed her Twitter name to Mrs.Petty but did not say whether a wedding had taken place.
