Supervisor at a new job immediately requested me on Facebook?

[Sleepy]

I know this can't be good. I have a personal life I like to keep away from work and just started a full time job yesterday. I have this problem everywhere I go. I start a new job and people want to get into my personal business. I have EVERYTHING set on private on Facebook because I want what I do on the weekends to be my business.

I have gone thru a nasty divorce and custody battle and I don't think it's office business. This woman is 30 years older than me. I don't want to hit "deny" because she is also my supervisor. I could end up in a tough situation where I offend her. Thoughts?
So when my friends tag me and them at a bar and this 60 year old woman shows my boss photos of me drinking it won't backfire like last time? I am 30. Last time I added a woman from work she gossip'd about everything I did to the office and I don't need the drama.
