Welcome to the Smart Set. Every morning we bring you the gossip coverage, filtered. Today: Jennifer Aniston and John McEnroe support Haiti and the art world, Kate Winslet could be Mrs. Ned RocknRoll, and Princess Cristina has a New York moment with Woody Allen.

  • Jennifer Aniston paid a record $450,000 for a painting by conceptual artist Glenn Ligon at the charity auction to benefit Haiti put on by Ben Stiller and David Zwirner at Christie's last night. She wasn't the only celebrity who dropped serious money at the auction. John McEnroe won "a sketch of Jay-Z at Glastonbury by Elizabeth Petyon for $85,000" and bid $240,000 for a piece by  Zhang Huan, which he lost. [The New York Observer]
  • Kate Winslet has reportedly turned her key on former boyfriend Louis Dowler and taken up with Ned Abel Smith, a nephew of billionaire Richard Branson "who rather eccentrically changed his surname to ‘RocknRoll’ by deed poll some years ago," according to The Daily Mail. Winslet and RocknRoll were weekend guests at Branson's Necker Island house when it burned down last month during Hurricane Irene. Something emerged out of the blaze, because when it came time to leave, RocknRoll went home with Winslet to New York. [The Daily Mail]
  • It's going to be hard for the diplomats and royalty visiting New York this week for the U.N. General Assembly to go back to the workaday world of international glamour and intrigue. Case in point: while having dinner with a friend Wednesday night at The Mark, Princess Cristina of Spain lost the thread of her conversation when she spotted Woody Allen in the vicinity. After her glimpse of the New York institution, a spy says the princess "giggled and whispered to her friend." [Page Six]
  • CBS' tribute to Bob Schieffer's 20 years as host of Face the Nation attracted a bipartisan crowed to the St. Regis Hotel in Washington last night. From the left side of the aisle, there was Minority Leader Nancy Pelosi (who left early), Secretary of Defense Leon Panetta, Rep James Clyburn, and Senators Pat Leahy and Amy Klobuchar. On the right: former Secretary of Defense Donald Rumsfeld, Rep. Darrell Issa, and Senators Lindsey Graham, Scott Brown, Kay Bailey Hutchinson, and John McCain, the guest with the most appearances in Face the Nation history. Media types in attendance included Bob Woodward, Ben Bradlee and Sally Quinn, Gwen Ifill, Judy Woodruff, David Snger, David Gregory, Margaret Carlson and a host of CBS News producers and executives, including chairman Jeff Fager and president David Rhodes.

  • If you've watched the ads for The Killer Elite and wondered which Hollywood idea man decided a good looking fella like Clive Owen should show grow a greasy, scraggly moustache for the film, we have a name for you: Clive Owen. "I looked at pictures of the ’80s, and everyone had mustaches,” Owen explains. “If you look at soccer teams -- any pictures from that period -- mustaches were big, so I felt I should go there.” Owen's logic was apparently enough to convince Robert De Niro that his character needed some facial hair too, and went for a full beard.

  • Kieran Culkin and Scarlett Johansson are not dating, despite being photographed on multiple occasions this month doing things that seem like dates, like walking the streets of Paris and New York arm-in-arm. According to the romance-denying source, they are "just old friends who went to high school together." Hence the arm-in-arm stroll in Paris. [Us Weekly]
