Cameron Diaz is reportedly preparing to move in with Alex 'A-Rod' Rodriguez.

The 'Knight and Day' actress - who has been rumoured to be dating the baseball star since April - has started publicly referring to the sportsman as her boyfriend and the pair are even said to be making plans to decorate a home in Florida together.

A source told Life and Style magazine: "While having lunch at Morandi restaurant in New York on August 19, Cameron was calling A-Rod her boyfriend.

"They're decorating his place in Miami together; now it can be a place the two of them think of as their home."

Cameron and Alex - who has previously been linked with Kate Hudson and Madonna - have been reluctant to be pictured together in public, but have enjoyed a string of private dates together at a number of top New York restaurants.

The source added Alex appears to be having such a great effect on Cameron that she is "looking better than ever" and has an "in-love glow".

The 38-year-old actress has previously credited her youthful appearance is down to "lots of sex".

She said: "I don't want to look 25 again. The fountain of youth for me, let's see. I guess it's exercise, healthy diet, lots of water, lots of laughter, lots of sex - yes, sex, we need that as human beings. It's healthy, it's natural, it's what we are here to do!"

Cameron - who has previously dated Justin Timberlake and John Mayer - has remained tight-lipped about her love life, however, preferring to state she is "in love with life".
