BOA BFFs!

Life's been busy for both Christina Aguilera and Nicole Richie lately. Xtina just split from hubby Jordan Bratman but, on the upside, she also just received a star on the Hollywood Walk of Fame. Congrats to the blonde bombshell! Her performance in Burlesque must be uh-mazing, right?

Meanwhile, Nicole Richie already has two beautiful kids, a successful fashion career and Joel Madden - what else could a girl want? A wedding, natch! The starlet is set to marry her man the first weekend of December... and Xtina might be performing at the big event!

So one can only imagine what these two lovely ladies discussed while lunching at BOA Steakhouse in West Hollywood this afternoon. We know one thing - they both looked gorgeous while doing it!
