Olympian Shannon Miller is pregnant with her second child. The most-decorated U.S. gymnast in history, Miller announced her pregnancy to fans via Twitter with the post, "For those on Facebook, John and I are exciting to announce that we are expecting baby #2 this summer! Time for more diapers!"

Miller is best known for her performance at the 1996 Olympics in Atlanta, Georgia, where she took home two gold medals — one for the balance beam and one as part of the best team performance for the U.S. Miller was the first American to win an Olympic gold medal for the balance beam.

Shannon's left ovary was removed and she underwent chemotherapy treatment from March 2011 to May 2011. In Sept. 2011 she confirmed she was cancer-free. Miller tweeted about her journey from cancer to baby earlier today. "Yesterday I celebrated 2 years post surgery to remove tumor. Today we are happy to announce we're expecting baby #2."

Miller explained her plans to have a second child with husband John Falconetti were delayed in 2011 by the ovarian cancer discovery. Shannon explained, "Things were going fantastic with the launch of my company, Shannon Miller Lifestyle, my foundation was growing and we hoped our family would expand as well. Then my world stopped. Instead of calling my parents to tell them they had another grandchild on the way, I was calling to tell them I may have cancer. Our baby plans were put on hold indefinitely."

Shannon continued, "I've been blessed to have the opportunity to do some amazing things in my life, but being a mom is second to none."
