London, April 11, Prince George and Princess Charlotte of Cambridge will be in aunt Pippa Middleton's May wedding, a statement from the Kensington Palace said on Monday.

"Miss Pippa Middleton and Mr. James Matthews are pleased to confirm their wedding will take place at St Mark's Church, Englefield, on the morning of 20th May," USA Today quoted the statement as saying.

"Prince George (who is 3) will be a page boy, and Princess Charlotte (2 on May 2) will be a bridesmaid," the statement added.

Kensington Palace has avoided commenting on other details of the nuptials because Pippa Middleton is not a royal, the report said.
