The actor — best known for 2009’s The Hangover — "is in love and is just waiting for the right time," says the insider.

And no wonder he’s cautious: The source says Bartha, 32, has proposed to Olsen, 24, in the past — "and she said no!"

Still, friends say the former child star (and twin to Mary-Kate) and the actor are a perfect match because they are so alike.

"Ashley has always been the more centered of the twins, and Justin is centered, too," says a second insider. "They mix well with each other's friends and calm each other."

And neither one’s hectic schedule bothers the other: "Justin’s a hard worker and sees acting as a business," continues the pal. "Ashley runs successful brands and has a strong work ethic."

They also seem to be on the same page as far as a wedding is concerned.

Says the first source, "They both want a low-key affair."
