No hard feelings here!

The best thing to ever happen to Casper Smart was dating J.Lo, so now that she's moved on with A-Rod, he still has nothing but nice things to say about his ex and her new beau.

Case in point?

The backup dancer called the MLB star a "legend" in reference to his baseball career, and says he has "nothing but respect and love" for the lovebirds.

These are some pretty kind words for someone that got left in the dust!

In other J-Rod news, the power couple are moving at lightning speed and have already decided to shack up together!

"J.Lo asked Alex to live with her in her $28 million mansion in Bel Air, and he agreed. The couple have barely spent a moment apart since they started dating and are ready to take things to the next level," a source dished to Life & Style.

"Initially she was concerned there would be a rivalry since the children are all so close in age and are used to being the center of their parents’ world. But as soon as the four kids met, it was like one big, happy family. J.Lo has always wanted to have a large family, so it’s a dream come true for her," the source added.

Her love don't cost a thing, but it's sure in demand!
