Jay-Z and Beyoncé Knowles sat courtside at a Nets game in Newark last night. Jay-Z, who is a part owner of the team, was all smiles with his wife despite New Jersey's loss against the Phoenix Suns. It was their second sweet basketball appearance recently after showing their spirit at the NBA All-Star game last week. Jay-Z and Beyoncé just returned from a bikini-filled quick trip to the Caribbean, but their getaway meant they missed the star-studded Oscars. There were plenty of other hot couples on hand for the event, though Beyoncé's pal and performer Gwyneth Paltrow arrived solo. She took the stage to perform "Coming Home" and later mingled with friends at the Vanity Fair afterparty.
