But if that shiny rock on her left hand in any indication, Adele might have even more reasons to smile in 2012.
In checking out photos of the crooner's multiple black dresses at the Brits, we can see pretty clearly that she's got two bejeweled rings on her left ring finger. One appears to be a simple band, while below it sits bigger ring with a flashy yellow stone.
We would be a bit surprised if Adele was already engaged. Not only did she wear an equally blingy but totally different rock on her left ring finger at the Grammys, but she also just made her first public appearance with her boyfriend Simon Konecki at the awards show two weeks ago.
But the two have been dating since last summer, which in celebrity time is at least a decade. Plus some of the more gossipy tabloids are reporting that Konecki's already been planning a proposal...
Do we hear wedding bells ringing?
Engaged or not, Adele was glowing in not one but two black frocks at Tuesday's show. Turning down the glam factor just a notch after her high-wattage Grammys appearance, Adele walked the Brits red carpet in a black floor-length gown with sheer sleeves and later took to the stage in a black knee-length dress with lace sleeves.
Both looked lovely, although neither matched the stunning glittering creation that was her Armani Prive Grammys gown.
Check out the finger bling (!) and her multiple dresses below.
UPDATE: Vogue UK reports that Adele's ring was on loan from DeBeers. More details: it's a DeBeers Solitaire Ring, featuring a 7.41-carat yellow diamond and two rare 1.58-carat diamonds, stacked alongside two De Beers Eternity Bands. Not too shabby!
