Jennifer Aniston was caught off-guard by proposal

Highlights

• The We're The Millers actress - whose 18-carat engagement ring came under fire last week with some critics calling it "too big" and "gaudy" - has revealed the surprise proposal was a "very covert operation" and she had no idea he was planning to pop the question on his 41st birthday in August.
• She told People magazine: "It's hard to pull one over on me, where I'm not like, 'Hmm, you're acting really strange.' It was ... a very covert operation."
• The 43-year-old actress also hit back at critics for suggesting her engagement ring is too big and insisted she loves it despite not selecting it herself.
• She said: "I was impressed. I had no idea, and I had no idea what I wanted. He just knows what I like."
• She said her fiance "worked with the girls that I have worked with for years and years and years, so he kind of was picking the specialists' brains. He kept it within a very small circle of people. It was one of the sneakiest jobs I've ever seen, actually."
• Jennifer became emotional when talking about her fiance during her first post-engagement interview with close pal Chelsea Handler last week and couldn't stop herself getting teary as Chelsea gushed about what a great couple they are.
• The surprise proposal - which took place just over a year after they started dating - occurred when the couple were dining at Greenwich Village restaurant Blue Hill in New York.
• After the proposal, an "overwhelmed" Jennifer - who was previously married to Brad Pitt - called her close friends and family to share the good news.
• A source said: "Just after Jen got engaged, she called all her friends and told them about it. She was so happy and said she loves the ring. I think she was overwhelmed and overjoyed by the size and beauty of it!"
