Honeymooners Earnhardt and Reimann certainly are -- despite a little snafu with lost luggage.

"I can't wait to see my luggage again! @Delta sent it on a personal trip of its own to get to our final destination. I hope," the 42-year-old athlete tweeted on Tuesday, to a prompt reply from the airline.

Earnhardt revealed that he and Reimann were engaged in June 2015.

"Looking forward to the rest of my life with this amazing girl," he tweeted at the time, while his ladylove shared a photo of the two -- and her engagement ring -- on the social media site.

"I'm completely overwhelmed with love and joy. Happiest girl in the world! I love you so much @DaleJr," she gushed.
