Is re-using FB reviews/ratings in Google schema.org markup ok? (star-rating snippet in SERPs) earn by blogging adsense income

Do anyone know if it's okay to re-use FB reviews/ratings in Google schema.org markup (for rich snippets in SERPs)? Or is it an issue with "duplicate content". Technically FB reviews are 3-rd party reviews. Does Google only accept 1st-party reviews for rich snippets? Thanks.
