Dale Earnhardt Jr. is engaged.

The 40-year-old NASCAR driver popped the question to girlfriend Amy Reimann during a family trip to Germany, USA Today reports.

The couple, who started dating in 2009, shared their happiness on social media this week.

As NASCAR.com notes, the news of the couple's engagement may indicate that Earnhardt has "gotten over -- or has it least gotten better -- at that whole being afraid of jewelry thing."

Earnhardt has previously admitted that he finds jewelry " creepy," but in a February interview, he conceded that Reimann could wear her engagement ring around him when the time came.

"We've talked about it," he told USA Today. "I'm not going to be held accountable [to wear a ring] and she can do whatever she wants. I figure if we ever get to that step in life, I owe her that much. I'll have to put up with [her wearing a ring]."
