H8 On Aubrey O'Day! Bitch Is Rude!

Sometimes we are reminded how ridiculously selfish some celebrities can be!

As we've posted, many celebrities are offering their support to the No H8, campaign and we've recently come to learn that Aubrey O'Day is one such celebrity. But, sources tell PerezHilton.com exclusively that Aubrey was anything but gracious or humble during the photo shoot.

In fact, she was a downright diva bitch!

The non-profit organization tries to accommodate its celebrity supporters to the best of their ability, but apparently that wasn't good enough for Aubrey. Sources reveal that she demanded that she bring her own hair and make-up team as "she wouldn't use the team provided" and that they be paid for! She also insisted on a car service to pick her up, claiming she had knee surgery and was unable to drive. An insider says that when she arrived "everyone was surprised she was able to walk and jump and what not in tiny ass boots."

Shady, shady Aubrey.

But it doesn't stop there!

The kicker was that though the car service was meant to just shuttle Aubrey to and from the shoot, she demanded that it stop off at a restaurant for her and her "glam squad" to eat and asked the driver to watch her dog while inside!

A source claims: "She told the driver she would take care of him but at the end of the night, she stiffed him!"

How incredibly disrespectful and conceited! Who does she think she is?

She's a D-lister at best!!!

Unbelievable.
