Britney Spears was at Alicia Keys' concert last night at L.A.’s Staples Center. And so were Nick Lachey and Vanessa Minnillo.

The show rocked. Man, has Ms. Keys grown into one fantastic jaw-dropping performer. Her voice filled that entire ginormous arena and then some.

During her show, Keys urged everyone to take out their cellphones and text the word Alive to the number 90999 to donate just $5 to help fight HIV/AIDS in Africa through the Keep a Child Alive organization. I did.

I sure hope Britney, Nick and Vanessa did, too.
