In the September issue of Vanity Fair, Jennifer Lopez admits that when it comes to love, she’s a glutton for punishment — or, in her words, an “eternal optimist.†She will say that she’s learned to walk away from something “when it isn’t right,†which is what happened when she and husband/collaborator Marc Anthony announced their divorce last month. The whole “walking away from something when it isn’t right†is a lesson she learned the hard way in 2003 following the release of Gigli. [NYT via AP]
