Cameron Diaz to Marry Jennifer Aniston's Ex?

Cameron Diaz is reportedly set to marry Jennifer Aniston's ex-boyfriend Paul Sculfor.

The pair -- who have been dating for several months -- were recently snapped together in the stands at the US open, struggling to to hide their love for each other.

Although Diaz has previously insisted that they have a very open relationship; and she was not yet ready for marriage, she and Sculfor are said to be planning a secret wedding.

"Cameron and paul have become very close very fast" a source told Britain's Grazia magazine.

"Things are moving faster than they thought and they're even talking about marriage."

Ex-construction worker Paul, 36, dated Aniston, 39, in 2007 but they split after a brief romance.

He then hooked up with Cameron who had just come out of a four year relationship with Justin Timberlake.
