Isla Fisher opened up recently about the baby she is expecting with fiance Sacha Baron Cohen. In her first public comments on the pregnancy, believed to be in its 7th-month, Isla said "I’m the happiest I’ve ever been in my life." The Wedding Crashers actress added that she’s experiencing some absent-mindedness, one of the more annoying side-effects of pregnancy.

Isla says she plans to lay low after the baby — rumored to be a boy — is born this fall.

The baby will be the first for Isla, 31, and Sacha, 35, who have been engaged for three years.
