Bieber Causes Row Between Couric and Dr. Oz

TMZ, you left out the most obvious question ...... why would either of them be doing at a Justin Bieber concert?

What the hell does "Causes Row" mean? TMZ loves making up there own language, just like teenage girls do.

The Bieb and the Wizard and the Wicked Witch of the West...on the ywllow brick road.

I think the real story is people actually going to see Justin in concert. I was given free tickets..(center, 8th row.) I had a hard time finding anyone over 10 years old who wanted them.

What is the attraction to Justin Bieber? He looks 12 year old. He's not that great a performer unless you are an adolescent girl. I just don't get it.

I can actually see Katie Couric being there. She reminds me of a clueless little Hannna Montana / Justin Bieber groupie type, but .... Mehmet Oz? C'mon, Doc!

DR. OZ IS SOOOO F'N HOTTT!!!!

I'd bang him in a heartbeat, no pun intended!!!! ahahahahaha!

Who is Katie Couric? She looks like my grandma.

RIP JB!! You will be missed!

WTF?

Dr. Oz looked really bored. Probably brought his daughter(s) there, but Katie really looked like a fan, lol

TMZ, you really have to get your sources and details straight. No "water bottle" was thrown. It was a t-shirt and a packet of sour patch kids. As much as people love gossips, you might wanna get your facts straight first.
