Jennifer Aniston still isn't used to her engagement ring.

The 'Cake' actress - who has been engaged to Justin Theroux for two years - has admitted that she's ''not a diamond girl'' but still loves the ring unconditionally.

She said: ''It's a rock, I know. He rocked it up. It took me a while to get used to it.

''I'm not a diamond girl. I'm more Indian jewellery and stuff.''

The 45-year-old actress also admitted that she thinks Justin, 43, was a gift from her dead ex.

Speaking of the unnamed man, she added to the New York Times newspaper: ''He was my first love - five years we were together.

''He would have been the one. But I was 25, and I was stupid. He must have sent me Justin to make up for it all.''

Meanwhile, the 'Friends' star also hinted that the couple may wed soon, revealing that they are having ''big discussions'' about marriage.

When asked if the couple had set a wedding date, she said recently: ''There's a big discussion in our house right now: Do you just do it and say screw it? Or do you try desperately to get away with [a secret ceremony] where you don't have any fun because you're hiding in a cave somewhere?

''If we could do it without all the buzzing and the noise...It can be done. Where there's a will there's a way.''
