Despite looking slightly, vaguely puffy in some recent photos, Britney Spears is not expecting a third kid. "U.S. pop singer Britney Spears says she is not pregnant for a third time despite recent photographs showing her with a bloated stomach. The 'Toxic' singer says a new medication she is taking was responsible for her recent weight gain and not a third pregnancy, the Daily Mail reported Saturday. 'I am not pregnant — it is just my medication that makes me bloated,' Spears said of recent pregnancy rumors. A source close to the 'Baby One More Time' star told the British newspaper Spears has struggled with her weight since the birth of her 20-month-old son Jayden James. Meanwhile, a friend of Spears said she is spending some time with actor Mel Gibson and his wife in Central America to help her gain some perspective in her life."
