Tyra Banks: 'I Wish I Was More of a Diva'

Tyra Banks may have gone from model to reality TV mogul, but she isn’t quite where she wants to be.

"I wish I was more of a diva," Tyra told Tuesday’s Nightline while talking about cast changes on America’s Next Top Model.

"I wish [I] was harder, I wish I didn’t care so much about being the nice girl all the time. Because a lot of the time people can take kindness for weakness … so I wish I had a little bit more 'oomph' in me."

Do you think Tyra is really a diva at heart?
