ATLANTIC CITY, N.J. -- Kim Kardashian and Kanye West are feeling lucky about their first child together.
"It's true," the 32-year-old reality TV star said in a statement on her site Monday. "Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us."
Kardashian's father, Robert Kardashian, died in 2003. West's mother, Donda West, died in 2007.
Kardashian added in the blog post that she was "looking forward to great new beginnings in 2013 and to starting a family."
The 35-year-old rapper revealed to a crowd of more than 5,000 in song form at a concert Sunday that his girlfriend is pregnant. Kardashian was in the crowd at Revel Resort's Ovation Hall with her mother, Kris Jenner, and West's mentor and best friend, Jay-Z.
The news instantly went viral online, with thousands posting and commenting on the expecting couple.
Most of the Kardashian clan tweeted about the news, including Kim's sisters. Kourtney Kardashian wrote: "Another angel to welcome to our family. Overwhelmed with excitement!"
West told concertgoers to congratulate his "baby mom" and that this was the "most amazing thing."
Representatives for West and Kardashian didn't immediately respond to emails about the pregnancy.
The rapper and reality TV star went public with their relationship in March.
Kardashian married NBA player Kris Humphries in August 2011 and their divorce is not finalized.
West's Sunday-night show was his third consecutive performance at Revel. He took the stage for nearly two hours, performing hits like "Good Life," "Jesus Walks" and "Clique" in an all-white ensemble with two bandmates.
Kardashian is expected to spend New Year's Eve at a public appearance at a Las Vegas nightclub.
