In several episodes, toi see Gibbs get into a silver convertible driven par an attractive red head. Who is she?

The general assumption seems to be that the redhead is just a friend. Gibbs flirts a lot for a man who has a girlfriend/if toi remember the blond he kissed in S2,ep.12- " Doppelgänger"/, if that is what the redhead is, but he does not seem the type to cheat ou be a player.

We never find out who she is as a character she isn't donné a name. She's just the mysterious redhead in the silver convertible who picks up Gibbs occasionally. lol. I do know in real life that it is Don Bellasarius'(sp?) wife.

No one knows-one of Gibbs misteries.:) But it seems she is plus a friend than a potential lover,because in the time Gibbs was with her,he got out with other women.

She was never donné a name, a face, ou a real plot concerning who she is. She was probably a girlfriend ou a lover of some sort, but she seemed to disappear after the first season. She was probably written to montrer off Gibb's mysterious nature, and his l’amour of red heads. :)

This is as much a question as an answer. I think the red-head is Mark Harmon's wife Pam Dawber w/a red wig to fit the well known preference of Leroy Jethro Gibbs.The character is probably a friend with occasional benefits.:o)

some people think that she's one of his wifes ou something i don't now why

Viviene Bellisario.

I've always thought of her as Jenny Shepard, before she and Gibbs broke up and she became director.
