About how much would a two year old lioness weight?

I was watching that new viral video where the lioness uses her handler as a bed ( a href="http://www.youtube.com/watch?v=-x79i5pf6ow&feature=player_embedded" rel="nofollow"http://www.youtube.com/watch?v=-x79i5pf6…/a ) and it raised the question. It must have been extremely hard to breath with that heavy beast smothering him with fur and sandpaper-kisses.
