On the morning talk show "Live With Kelly and Michael," Franco said Friday that he used "bad judgment" and "learned my lesson."
The 35-year-old actor and filmmaker was caught trying to pick up a Scottish teenage girl named Lucy Clode on the photo-sharing app.
Franco said Friday that he was embarrassed and that he's "a model of how social media is tricky." He said the awkward process of meeting someone was made "doubly" embarrassing since it was in the public spotlight because of his celebrity.
Franco is currently starring in a revival of "Of Mice and Men" on Broadway.
