I did a search on the phone number and found pics on Backpage in LA which jives with the area code.
The bad news is it wasnt Tatiana and I couldnt scrape up a reveiw of her or any other one else with that number anywhere.
Could be real but chances are iffy at best.
Most likely a sketchy agency ..if thats the right word.. I'd pass pending some sort of varification...sorry as the pic is intriguing to put it mildly.
