Avril Lavigne and Deryck Whibley were seen leaving the Brass Monkey Karaoke Bar.  I wonder if either of them did karaoke to their own songs, how funny would that be???  Avril must have enjoyed herself because she's actually smiling for the paparazzi...now that's not something we see too often! And did anyone else notice...Deryck is wearing literally, the exact same outfit he had on the last time we saw him.  The only difference is that he swapped out the black jacket for a jean jacket this time.
