The 52-year-old George Clooney got down on his knee last week after cooking a romantic dinner at his mansion in Studio City, and presented Amal Alamuddin with a stunning 7-carat ring that he personally designed, reported New York Post online.
Clooney hopes they can marry in just a few months, even as early as the beginning of September.
"George cooked a meal himself for Amal at home on April 22, then he surprised her by getting down on bended knee and presenting her with the ring. He was so happy she accepted, he was calling friends with the news later that night," a source said.
The night after the proposal, the couple joined friends for dinner at Craig's restaurant in LA, where, according to reports, the lovebirds were "just beaming".
A similar scene took place at Nobu in Malibu the following night, April 24, with friends Rande Gerber and Cindy Crawford, where Alamuddin was seen happily showing off her ring.
The couple could wed at Clooney's Lake Como, Italy, estate.
"Lake Como would be a beautiful wedding location, but it may not give them any privacy. It is very easy for the public and paparazzi to see into the property," the source added.
Clooney's representative has refused to comment on the engagement and nuptials.
