According to HollywoodLife Rob was spotted at Brit songstress Adele's concert at the Greek Theatre in downtown LA.
Quality choice, Rob - there's no denying Adele's talent. For TwiCrackers who might have been living under a large (sound-proof) rock, please enjoy the above video for your musical education.
Randomly, I was in LA today and saw the lines for her show winding around the block!
I also popped into the Chateau Marmont for lunch... no, I didn't spot Rob but now I wonder if he was around ;)
