Hi! Met a Hb9 on a house party last saturday, and we connected directly. Spent the while night touching eachother, but no sex because we were in a 1 room apartment with two other persons in the same bed..
We Said goodbye in a hurry early in the morning and i forgot to Take her number

Found her on Facebook Teo days later and added her. Now to the question, how should i close with her? Just send a message on Facebook asking for her number, and then move on to texting or calling her? Or chat with her for a while on Facebook, then ask her to mest me up for a cup of coffee?
Usually know how to do it, but this girl is kind of special, she's kind of famous ( Done some acting, got a Blog and like 5000+ friends on FB and 60k+ followers on instagram).
And also, she's 17 and I am 20.
