Longtime loves Diane Kruger and Joshua Jackson stepped off a flight from France today -- both in sandals -- after a whirlwind time at the Cannes Film Festival.

The pair, who've been together for six years, won't be walking down the aisle together anytime soon, according to the 35-year-old Jackson ...

“Neither of us is religious, and the picket fence isn’t what we're aiming at,” the 33-year-old actor told Life & Style magazine. “We’re together for six years now, so for all intents and purposes, we are (married).

“I have no need for a priest to tell me that!”

Kruger, also 35, was previously married to French actor Guillaume Canet for five years. The two divorced in 2006.

“Without sounding pessimistic, I learned that I don’t believe in marriage,” the actress told Glamour magazine in February 2011. “I believe in a commitment that you make in your heart. There’s no paper that will make you stay.”

Jackson recently gifted his actress girlfriend with a $45,000 necklace, sparking engagement rumors, but it sounds like, in this case, a gift was just a gift!
