Hilton in trouble after Steve-o confession

TV stuntman Steve-o has landed Paris Hilton in hot water after confessing he "might have given her some mind-altering substances" just minutes before her November car crash.

The outrageous former Jackass star appeared on America's Jimmy Kimmel Live show on Thursday night and candidly revealed how he spent a night with the hotel heiress and her boyfriend Stavros Niarchos III.

He told chat show host Kimmel: "I walked into this nightclub to go and meet her and her billionaire boyfriend. I was just clinking and clanking with little nitrous (oxide) cartridges and filling up balloons - I probably shouldn't say that, but whoops!

"It's funny (but) half an hour before Paris Hilton had that car crash I might have given her some mind-altering substances."
