WHITNEY BACK TO HER OLD WAYS?

We hear Whitney Houston was back to her bizarre ways at the Hopkins-Calzaghe fight in Vegas Saturday.

"She was practically carried in by her staff, and her people snapped their fingers, saying, 'Whitney needs a waitress!' " reports the NY Post. "She couldn't focus while Ray J sang the national anthem. But when he got back to her they were lovey-dovey all night."

Let's hope she's not back on that stuff.
