Better hope Joshua Jackson isn't trying to "pop the question" to girlfriend Diane Kruger — because it's the worst kept secret in Hollywood! For example, he was apparently shopping for engagement rings recently at Neil Lane in Beverly Hills, Calif.

"He was looking at an $80,000 3.5-carat emerald-cut platinum engagement ring," an onlooker tells Life & Style. “He thinks it’s perfect."

The 35-year-old actor rose to fame in Dawson's Creek — and flicks like Cruel Intentions and The Skulls — and most recently appeared in the cult sci-fi show Fringe.

Diane, meanwhile, is famous for her roles in movies like Troy, National Treasure, and Inglourious Basterds. This summer, in FX's The Bridge, the 36-year-old takes on the role of an American detective with Asperger's who teams up with a Mexican detective (played by Oscar nominee Demián Bechir) to investigate the deaths of two murder victims whose bodies are found on the U.S.-Mexico border.
