Aaron Paul may have played a badass on "Breaking Bad," but he's really a softy! 

The actor just helped make one already-epic proposal much more memorable, by sending a sweet video message.

Check out the video above to see Aaron's special cameo in Jason Lord's the over-the-top proposal!

Jason met his now-fiancee Jackie Prater three years ago, and on one of their first few dates they sang a drunken duet of Mr. Big's "To Be With You." 

With the help of a few of Lord's friends, he performed the song for Jackie before popping the question.

But that wasn't even the best part! Jason -- who donated to Aaron's wife's charity -- asked the AMC star (who is Jackie's favorite actor) to cue the proposal with a personalized intro. 

We've gotta say -- that was a pretty awesome move on Paul's part!

But the actor isn't the only star who's helped someone pop the big question recently.

Over the weekend Justin Timberlake let a fan take the stage in the middle of his concert to propose to his girlfriend!
