World no. 1 tennis player Serena Williams was watching golfer Tiger Woods at the PGA Tour Honda Classic on Friday and got herself in a little bit of trouble.
The 31 year old tried to take a photograph of the former world no. 1 golfer on her mobile phone but then found herself in a spot with security officials at the event.
Under PGA rules, spectators are not allowed to take pictures or video of players on competition days.
Soon after, Serena tweeted to her followers on Twitter, "Apparently you can't take pictures of golfers. In my defense peeps always take pics of tennis players."
Serena will not play next week's BNP Paribas Open in Indian Wells. She has not played there since 2001 when fans booed her and she alleged they hurled racial insults at her and her family. She will next appear at the Sony Ericsson Open in Miami.
Serena recently regained the world no. 1 ranking - having won two of the last four grand slams - and at 31, is the oldest woman in tennis history to be ranked at the top of the sport.
