Kim Kardashian is expecting her first child with hip-hop superstar Kanye West, according to an announcement made Sunday night that sparked a message-sending frenzy on Twitter.

Kardashian, 32, and West, 35, have been dating since last April, about five months after she began divorce proceedings against NBA player Kris Humphries 72 days after their extravagant and televised wedding.

West announced Kim's pregnancy during a performance before 5,000 fans Sunday night in Atlantic City, New Jersey.

Kardashian achieved notoriety in 2006 when she appeared in a sexually explicit videoclip that resulted in her receiving a court settlement of $5 million.

In 2010, she starred in a reality show, earning some $6 million.

West rocketed to fame as producer of Roc-A-Fella Records as well as for his own musical talents, which have won him 18 Grammys and allowed him to sell more than 30 million digital downloads of his songs in the United States. EFE
