A question about Roger Federer and his wife?

Roger Federer 28, married his public relations manager Miroslava Vavrinec, 32 (an average looking fatty) in April 2009 and had gave birth to his twins in July 2009.

Could it be possible that he was tricked? That she decided to celebrate his win with a little boom boom and lie about taking the pill, got pregnant and blackmailed him into marriage?
Emotional blackmail?
