Charlie Sheen’s fiancee Brooke Mueller has said she was stunned when the actor proposed last month.

Charlie presented her with a $500,000 engagement ring during their holiday in Costa Rica and she told People magazine recently: “I was totally caught off guard when he popped the question!”

“We were having a romantic dinner in the hotel room with room service when he asked me to marry him. I was thrilled. I smiled all night and kept looking at the ring because it was so beautiful.”

Brooke added that she wants “a big wedding” but not just yet: “We just got engaged and both of us want to enjoy the journey right now. We really want to live this part of our lives.”
