Serena Williams spent part of her Friday at the Honda Classic, where she followed Tiger Woods for a little bit. The tennis superstar – who lives near PGA National, where the tournament is being played – wanted to take a photo of Woods with her cell phone, but an ever-vigilant marshal caught her in the act.
Amazingly, someone caught the incident on video, and you can see it here. 
Williams admitted her infraction later on Twitter :
@serenawilliams: "Ok at this Golf tournament. Just saw @tigerwoods I understand NO golf Apparently u can't take pics. This security for mad and yelled at me''
She did, however, get her photo, and she shared it – it's the one posted above. You can see her original here. 
And she added:
@serenawilliams : ''I need to learn golf dident know I knew so little. Apparently u can't take pictures of golfers. In my Defense peeps always take pics of tennis players.''
