Prince Charles and Camilla Parker Bowles are visiting the United States and have so far explored Washington, D.C.

They plan to visit President Obama and Vice President Biden Thursday. Even with all of the happenings in America, Prince Charles is a little distracted with some events back in England.

Prince Charles and Camilla were mobbed with questions regarding the second royal baby, expected to come into the world in April, NBC reports.

Duchess of Cambridge Kate Middleton confirmed that her baby's due date is the "mid to end" of April.

NBC News' Peter Alexander asked Prince Charles what he thinks about a new baby.

"Prince Charles, are you excited to be a grandfather again?" he asked.

Charles smiled and said, "Oh yes!"

Prince Charles and Camilla will spend one more day in the U.S., heading to Louisville, Kentucky on Friday. Then, they will head back to the U.K. to help Middleton and Prince William get ready for the new baby, according to E! Online.

Prince William and the duchess will keep the gender of their new baby a mystery until the day he or she arrives.

Middleton visited a children's center Wednesday where she confirmed her anticipated due date in April. At the Brookhill Children's Centre, Middleton spoke with volunteers, including Christie Osborne. Osborne complimented Middleton for her appearance and her "tiny little bump."

Last month, Middleton told a teenager at the opening of the Kensington Leisure Center that she can feel her baby kicking, E! Online reported.

"It's moving all the time," she was quoted as saying. "I can feel it kicking now," Middleton said.

Middleton and Prince William's first child George is now 19 months old. They did not find out his sex until the day he was born.
