Judging by photos of the actress this week, it looks like he was right.
Megan's usually flat stomach was replaced by an unmistakable bump, which she rubbed as she walked along in the sunshine.
A closer looked revealed her to be wearing an 'angel caller' necklace often worn by women during pregnancy.
The pendants consist of a metal sphere containing a chime which should be worn at belly button level.
As the chime sounds when the expectant mother moves, it is said to call on angels, dissolving negativity and bringing love and protection to the baby.
Once the new arrival makes an entrance the charm is then hung above the crib, soothing the baby to sleep with same sound the little one heard throughout the pregnancy.
Sources are already saying Megan is expecting a daughter with her husband Brian Austin Green.
The little girl would be a little sister for Austin's ten-year-old son Cassius, from his relationship with Vanessa Marcil.
