SO HAPPY TOGETHER

Nicole Richie proudly showed off her eye-popping (engagement?) ring as beau Joel Madden escorted his gal out of Mr. Chow after dining at the Beverly Hills hotspot.

The happy couple has thus far remained mum over their relationship and rumoured engagement, but something tells me that we should expect a big announcement sometime in May, just when 'The Simple 5' promo campaign kicks off.
