Besides the content locker, get them to sign up for a weekly email about the most shocking celebrity news and pics.
Make sure to get them to specify their country and their gender when they sign up.
Find an info product or some other product that will convert for each country for the niche that they're interested in (celebrities). Send them to different lists using mailchimp for each group that they fit into.
If they are US, for example:
Men: An infoproduct about how to get a date with a movie star
Women: Infoproducts like a secret celebrity diet, celebrity workout secrets, celebrity makeup secrets
Hit them with an autoresponder series with a well written campaign for each product, starting after you give them some great free tips. Might want to pay someone to write these emails for you. Voila.
