The David Letterman Sexy Scandal has yet more "sordid" mundane details to be wrung out of it. Details about sex, between David Letterman and a lady! The same lady, Stephanie Birkitt. But more incidences of sex!

Hugh Jackman playing with his kids outside ... Blake Lively filming scenes for Gossip Girl with Chace Crawford in Central Park ... and Orlando Bloom eating lunch with Miranda Kerr at the Central Park Boathouse.

Executives at Wall Street firms that did not receive bailout funds from Washington (or have since paid it back) seem to be expecting to do fine this year: According to a poll by eFinancialCareers.com, "more than a third of Wall Street finance professionals surveyed expect their bonuses to increase for 2009." Those who work at Citigroup or Bank of America won't be as lucky, clearly. In what the Wall Street Journal describes as the most "intrusive" move into corporate compensation (but which others might just call "pretty reasonable"), pay czar Ken Feinberg revealed today plans to "clamp down on compensation at firms receiving large sums of government aid by cutting annual cash salaries" and shifting a chunk of it into company stock.
