O’s b’day blowout

PRESIDENT Obama’s final birthday celebration at the White House was a “blowout,” said a guest. At POTUS’ 55th birthday party were guests including George Lucas, Nick Jonas, Ellen DeGeneres, Magic Johnson and Sarah Jessica Parker. Stevie Wonder and Usher performed, and “everyone egged on Sir Paul McCartney to sing,” a spy at the bash organized by Michelle Obama said. Also at the party were entertainment execs Alan Horn, Ted Sarandos, Harvey Weinstein and Richard Plepler, designer Michael Kors, hedge funder Marc Lasry, Chicago Mayor Rahm Emanuel, NBA star Chris Paul, and hip-hop artists Common, Kendrick Lamar and Timbaland.
