The TV star was waiting backstage at the live show when her baby reminded her she was a month away from giving birth.
Landry says, "They're called Braxton Hicks contractions. I'm walking into the studio and then the belly just really tightens up like a rock and you kinda feel like you're gonna give birth. It lasted a few seconds."
And the actress faces a nervous film shoot in two weeks - because she fears she'll go into labour on the set.
The Sunset Beach star says, "I have to go and shoot my part of the film in two weeks, which will be very close to the birth, and the only reasons the doctor's letting me go is because they (producers) will have a helicopter on set ready."
