Actress Jennifer Love Hewitt has once again been forced to deny reports she is expecting her first child. The Ghost Whisperer star has been at the centre of pregnancy rumors since she was pictured in a bikini last year sporting a slightly fuller figure.And the 29-year-old - who is engaged to Scottish actor Ross McCall - sparked further gossip when she arrived at Saturday's Nickelodeon Kids' Choice Awards wearing a maternity-style dress. But the star has now dismissed the reports, with her representative telling People.com, "She is not pregnant."
