Albert told German television station ZDF this weekend that Saint Nicholas Cathedral, where his parents Rainer III and Grace Kelly tied the knot in 1956, was too small for the planned ceremony.
The royal couple did not reveal many details on the ceremony; however, People magazine said Sunday they indicated children were a possibility down the road even though Albert is 52 years old.
"I personally want to have children," Wittstock said. "I love children, and I simply can't wait to have a family of my own."
Albert replied, "I agree."
