Is there trouble in paradise for Diane Kruger and her longtime boyfriend, Joshua Jackson?

The actress posted a cryptic quote about love and relationships to Instagram on Tuesday which has fans worried that things might have ended between the couple.

"Men aren't stupid, and you don’t need a complicated set of rules to find a good one who loves you," Kruger quoted. "Here's the only rule you need: If a man loves you, he will do anything he can to keep you around. Anything."

"I hate inspirational quotes and yet they can be like cheap wine... hard to resist every once in a while," Kruger captioned the post. "So I'm sorry...suck it."

She also shared what appeared to be a somber snap of herself laying down on a couch while biting her thumb, which she captioned: "Mood."

The National Treasure star and her 37-year-old beau began dating in 2006, and have stayed relatively private about their relationship and personal lives.

In December, rumors began to swirl that Kruger was romantically linked with The Walking Dead's Norman Reedus after the two were allegedly seen making out at a bar in New York City. However, a source close to the actress told ET at the time that Kruger and Reedus are just friends, and that she was still with Jackson.
