But those reports just aren't true, Leung said.
"She just knows what she wants," Leung told Contact Music about Watson, according to Daily India. "She's very confident and so intelligent. She got so many A-stars in her exams. I don't know how she manages it."
Apparently Leung had more important things to worry about while filming, especially about one scene where the Scottish actress said she had to pucker up for Harry Potter star Daniel Radcliffe.
"We didn't practice beforehand because it's supposed to be a pretty awkward moment," Leung said. "It is his first kiss, so it's not perfect."
And that awkwardness should put many viewers of the upcoming film -- no matter what their age -- down memory lane.
"Hopefully when people see it, they will think back to their first kiss," Leung said.
"Harry Potter and the Order of the Phoenix" opens worldwide July 11.
