These surprise visits are getting to be a regular occurrence. First it was eating at Chick-Fil-A in Laguna Niguel. Then it was the Biebs popping into the normally 21-over La Cave to sing with Ernie Halter. Now we find out that Justin Bieber was at the House of Blues in Anaheim last Sunday to show support for Joseph "Rev Run" Simmon's son, Daniel "Diggy" Simmons and LilTwist. Soon after the 10-minute appearance (where they performed "Wind It") Bieber tweeted, "#supportyourfriends #SWAG."
