Sticky post of current viewing author?

I find what was missing ($wp_query->queried_object_id;), here is answer:

$current_browsing_author = $wp_query->queried_object_id; // Get current browsing author
$sticky = get_option( 'sticky_posts' ); 
rsort( $sticky ); 
$sticky = array_slice( $sticky, 0, 5000 );
query_posts( array(
'post__in' => $sticky,
'author' => $author,
'orderby' => 'rand',
'post_type' => 'post',
'post_status' => 'publish', 
'posts_per_page' => 5,
'caller_get_posts'=> 5
) );
