Valentine's Day will heat up once again with the release of the final film in the Fifty Shades trilogy. 

And the latest trailer was released yesterday during the premiere of the new season of the Bachelor in the US. 

What do we discover? 

Well there is mention to Anastasia Steele / Grey falling pregnant... Watch the moment she finds out. 

Plus we see one hell of a rock in an engagement ring, and PLENTY of drama. 

Brace yourself, this is going to be one hell of a ride.
