Does he like this girl?

I am good friends with a guy who ia a theater/tv actor. He is quite an established actor on TV and is a one of the hearthrobs among girls these days.
Hes 29. And single. Hes a different type of guy. Reserved and quiet type though he has a fun loving side too.
Hes pretty intellectual. And he has a good character. Never has any involvements with any of his female actresses.

But recently in a mythological show he is doing, he is paired opposite a new girl.
The new girl is 23 years old. And shes completely new. Has no modeling or acting experience.
She was chosen soley on the basis of her looks and acting in her audition. Shes quite pretty. And he has lots of scenes with her so they rehearse together.
And he is super flirty with her. She brushes it off but hes always flirting with her and complimenting her. Something he NEVER did.

Many guys of the show seem to like her and particularly the lead actor is fawning over her. Which my friend does not like. He said hes posessive about her as his 'costar' but why possessive about her if shes just a co-actor?

The girl is best friends with a female coactress and she never pays attention to them but my friend is always watching her. He says shes very cute and intelligent. And he can relate to her.

They have their birthdays in July. Both of them. And they hail from the same state as well.

Does he like her? I m jjust asking so no judgement.

Why do you care? Mind your own business

Ya sure as shit he has finally met someone that sweeps him off his feet. He is totally smitten with her. Who knows, maybe it will hit the tabloids next week.

Which actor?

Is he an actor in the USA or another country because you said mythological show? It sounds like he likes her and lots of costars hook up it doesn't mean it lasts but it happens a lot.
