Talk about a marriage dream going down the drain!

ANGELINA JOLIE got so scared of losing the stunning million dollar$$-plus engagement sparkler BRAD PITT had slipped on her finger that she ordered jewelers to craft an exact replica of the 10-plus carat ring following a scary accident.

After getting grubby with her kids for an art project, La Jolie put the ring on the sink, began scrubbing her hands and…OOPS!…knocked it into the basin.

Luckily, her lightning-quick reflexes saved the day – Hubba Hubba snagged her rock of ages just before it went swirling down the drain.

She’ll now stick with her fabulous fake for all but the special-est occasions.
