"When you reach the top, that's when the climb begins," is one of Michael Caine's most memorable quotes. But the 80-year-old actor hasn't been alone in his ascent -- he has had his wife, Shakira Caine, by his side since they were married in 1973.

Michael Caine and his wife recently celebrated their 40th wedding anniversary. Caine credits his decades-long marriage as one of the things that keeps him feeling young. As stunning as Shakira is at 66, "you should have seen her when she was 24," Caine told the Mirror.

A photo posted on Reddit of Caine and his wife in 1973 today got us wondering just what the Caines looked like in their younger years; we found some great images, like the one below.

The two were connected through a mutual friend after Caine saw the former Miss World finalist in a Maxwell House coffee ad. Caine was ready to fly out to Brazil to find the beauty, but as fate would have it, Shakira only lived a mile away, Caine told The Mirror.

Now, 40 years later, the pair are just as in love as they were when this photo was taken. They keep the romance alive by taking weekend "honeymoons" to Paris, Caine has said.

For more photos of the Caines in their earlier years as a couple, take a look at the slideshow below.
