Cameron: Still Holding Out for Matt Dillon!

They may have broken up 10 years ago, but friends say Cameron Diaz has been holding a torch for former flame Matt Dillon all this time.  Yes, she's dated some Hollywood hotties, including Jared Leto, Justin Timberlake and now, model and Jennifer Aniston's ex, Paul Sculfor.  But pals say the leggy blond never really got over her first true love-- and now her feelings for Dillon could be getting in the way of her current relationship!

"I'm sure she still thinks about him--a lot," Cam's friend tells OK!.  "Cameron looks bored with Paul. He must not hold her interest.  I seriously doubt they'll last much longer."

Especially with the sudden death of her father, Emilio Diaz, on April 15, Cameron has been reevaluating her life, reminiscing about her most meaningful relationships.  Cameron, 36, met Dillon, 44, on location in Minnesota in 1995.  At the time, Matt was filming Beautiful Girls and Cam was shooting Feeling Minnesota.  They later teamed up for the 1998 comedy There's Something About Mary.  Things got serious, and then suddenly that same year, the couple split.

Dillon later admitted to Parade  Magazine in 2006, "I fell in love.  It's a very powerful thing when you feel that way about somebody."

Since breaking up with Diaz, Dillon hasn't dated anyone seriously and, despite her three relationships, Cameron still seems unsure of settling down.  As OK! previously reported, Cameron seemed thrilled when she and Matt ran into each other at the Chateau Marmont in March. "When she spotted him, she ran over and gave him a hug," an eyewitness said.
