Spears Dumps Aldridge For Older Man - Reports

A report on StarMagazine.com suggests Britney's little sister ditched Casey Aldridge in December (09) and has been romancing 28-year-old businessman James Watson.

Jamie Lynn,18, provoked a storm of controversy back in 2007 when she revealed she and Aldridge were expecting a child - daughter Maddie, who is now 19 months old.

But that love affair came to an end last year (09), reportedly sending the teenage actress into the arms of Watson, who owns his own communications company near Spears' Louisiana hometown.

A source tells Star, "They started dating last December. I don't think James cares at all about who she is; they really seem to like each other."
