It is
maybe less current in North America but in Europe, mainly in France, some do get popular doing something else after porn even tough everybody knows their past.
Catherine Ringer. She did some of the most heavy types of harcore scenes (being pissed on and shitting on some guys) and she became the singer of a rock band (quite good) called Rita Mitsuko. At one point it was the most popular French rock band.
Dolly Golden is now starting to play in mainstream movies and had a good scene (not sex scene of course

) with Thierry Lhermitte one of France most popular mainstream actor.
I know another girl (damn it, I don't remember her name) that hosted for a few years a TV family show at prime time hour. Now she is doing the same show in Spain.
Virgine Gervais, the ex miss FHM France became even more popular when the fact that she did a porn clip a few years before the FHM contest became known and the clip shown all over the net. Since then she stated her own website, is playing in mainstream movies and is a regular guest on TV shows and she still continues to do a few porn clips once in awhile.
That's then one I remember at first tought.
But the contrary exists also but maybe even less often : going from being known in mainstream to porn. The most interesting case (to me) is Nancy Lee, A Hungarian opera singer known in her country, that quitted opera to do porn in Italy.
