Rachel McAdams, no nip slip this time, at the Guggenheim Artist ball

After playing out a storybook romance on the big-screen, 'The Notebook' co-stars Ryan Gosling and Rachel McAdams appear to be heating things up in real life. The couple has sent rumor mills spinning after the two were reportedly seen shopping for engagement rings, so says imdb.com. A friend of the couple tells the Chicago Sun-Times, "Not only does it look like they're living together, but they've been talking to top private jewelers about engagement rings." [AZCentral]
