Leonardo DiCaprio sat near Mick Jagger and his young son Lucas to watch the World Cup quarter final match between Germany and Argentina yesterday in Cape Town, South Africa.

During the match, Leo was spotted making a "Titanic" noise on a Vuvuzela!  Lucas is Jagger's son with Brazillian model Luciana Morad.

In a World Cup shock, Argentina lost 4-0 to Germany, setting them up for an all-European semi final (and repeat of the Euro 2008 final) between Germany and Spain.
