Jeremy Piven: Sincerely Sweet or Smooth Talker?

Actor gives showbiz advice to a group of aspiring young ladies at an L.A. coffee shop and then asks one of them for her number. Surprised?

From questionable sushi stories to the company he keeps, you might say Jeremy Piven has developed a bit of a rep for himself. So the following should come as no surprise:

While sitting solo with a cup of coffee at Toast Bakery in West Hollywood on Friday, a group of young women happened to catch his eye.

According to an E! News source, the actor asked the two brunettes and one blonde, "Is it OK if I join you?"

Pulling up a chair, the Entourage star immediately turned on the charm while talking to the aspiring starlets about breaking into the biz…

"He was beyond sweet," the source tells us. "He gave really great advice and was a total gentleman, even picking up the tab."

Then after about an hour together, Piven casually asked the blonde for her number, who was more than happy to oblige.

Of course, it remains to be seen if he'll be calling her for a date or offering her, say, a gig on his show.

Or simply not calling at all.
