Ooops, yeah sorry OP....... This is very unprofessional and inappropriate. You don't mix business with pleasure, or bleat about work stuff/professional stuff out of work to other people.
A doctor's receptionist at my old practice used to think it was funny to make silly comments about the amount of meds someone had (Shirl who was a neighbour of her aunt, who she knew her from 20-odd years back.) EVERY time Shirl came into the practice, this woman said 'here's Shirl, shuffling in for her 2 foot long prescription' with a massive
on her face.' 'Shirl' was never amused, just embarrassed. The other women on reception looked a bit 
One day in the town centre, she said 'hiya Shirl, got your pull along shopping trolley for all your inhalers and anti inflams and cocodomol LOL!?'
'SHIRL' was not impressed, and went straight to the practice manager at the doctors surgery, and put in an official written complaint about her. This complaint - along with the fact the other receptionists had heard her before - resulted in a written warning that stayed on her employee record for a year.
By the way, there are no 'moronic' responses on here. Anyone who thinks what the OP did is OK, is laughably clueless, and clearly knows jack-shit about recruiting, HR, and management, and DATA PROTECTION. Please tell me you are not in a position of trust! 
At my place, there would be a disciplinary for such a gross data breach.
Incredibly silly to do this. I know the OP meant well, but I am cringing for her. And to say 'I sung your praises...' Jesus!' 
Please do not contact this woman again. And if you see her, don't mention it. And do NOT mention to anyone that you messaged her. As a number of posters have said, it could spell trouble for her in the future. It may be advisable (as someone suggested,) to tell your manager what you did, and that you meant well. Because it's possibly going to come out. Better that you fess up first!
Also agree that the woman will possibly think she only got the job because you 'put a word in for her!'
