Karrine Is Running Her Mouth About Shaq!!!

Shaquille O'Neal wants his wife's finances investigated, he said in divorce papers filed Tuesday. But Karrine Steffans remembers him as being very generous.

"On the first date, he gave me $10,000," Karinne Steffans told us yesterday. "Over four months, [he spent] more than $40,000 on me, as far as I can remember."

The infamous "Video Vixen" said she had a relationship with O'Neal after he became engaged to his soon-to-be-ex-wife, Shaunie.

Which makes it awkward when she runs into the wives — like she did with Mrs. O'Neal in July.

"Just recently at the ESPY awards," she chuckled, "we both had the same hairstyle and everything."
