Is she 69 years old

Uh what? She's gorgeous and funny to boot.

She is either 26 or 27 years old (she was 8 years old when she did her first scene in ER)

By Hollywood standards, having not made the big time by around 30 would be considered old. Otherwise, she's still fairly young by society standards. I believe her biggest obstacle is her name. I would shorten it to Milana Vayn, or Milana Vana. Otherwise, Vayntrub doesn't exactly flow from the tongue. Hey, she can do no worse than the rest of the so-called talented actresses out there. If Aniston & Cameron can have careers, so can she. Look at "Flo" from the Progressive commercials. She not only has instant fame recognition, but will make more money from those ads than any other medium.
