The actress was shocked when Justin got down on one knee

Jennifer Aniston was shocked when fiancé Justin Theroux proposed to her in August.

The actor popped the question on his 41st birthday – and Jen was thrilled with the huge diamond rock he chose for her.

‘I didn’t know what I wanted for a ring. He just knows what I like,’ says Jennifer, 43.

‘The proposal was one of the sneakiest jobs I’ve ever seen. I had no idea.’

Jennifer – who describes Justin as a ‘beautiful partner’ who brings her ‘a lot of joy’ – has been keeping very quiet on the couple’s wedding plans since they became engaged.

But the actress has hinted that her wedding dress will channel her classic sense of fashion.

‘A bride should look like herself. Just be yourself,’ Jennifer tells People.

‘If you try something new, you’ll feel uncomfortable.’
