Cameron Diaz flashes 'engagement ring' on TV show

Cameron Diaz is letting her new jewelry speak for her after flashing what appeared to be an engagement ring during her appearance on TV show Late Night with Seth Meyers on Friday (19Dec14).

The actress has yet to confirm reports suggesting she and rocker boyfriend Benji Madden are planning to wed - but she offered up a big hint the story is true while promoting her new film Annie last week.

Diaz, who was also sporting a punky nose stud, swept hair out of her eye multiple times using her left hand, showing off a huge diamond sparkler on her ring finger, but made no mention of her rumored engagement during her chat with Meyers.

Last week, sources told Us Weekly magazine Good Charlotte star Madden, who previously dated Paris Hilton, popped the question recently after a seven-month romance with the Charlie's Angels star.

Diaz's ex-boyfriends include Justin Timberlake, Jared Leto, baseball superstar Alex Rodriguez and British model Paul Sculfor.

Madden has also romanced Australian model Sophie Monk.
