THE RING!

It's the most talked-about accessory of the year! The ring Lopez flaunts in the "Jenny from the Block" video is the real deal – a 6.1-carat pink diamond from Harry Winston, which Affleck had custom-made for Lopez. The two keep their engagement a secret until Lopez spills the beans to Diane Sawyer in Nov. 2002.

And I just admire him in every way."
