Speaking to Entertainment Tonight, he said: ''Anybody who's ever seen the two of them together, it's like, 'They getting married. Yeah, they getting married. That's going to happen.'

''I found out the same way everyone else did. I looked on Instagram and saw and went, 'Oh, it finally happened!'''

''Then I instantly sent her a text saying, 'Congrats, congrats, congrats,' and she said, 'Thank you, thank you, thank you.' And, I said, 'OK, y'all are doing engaged stuff, you go do that.'

''I'm super happy for her. She's over the moon. She really is. You can totally tell. I won't say it's the happiest she's ever been - I don't personally know - but it's the happiest I've seen her since I've known her, so that being said, good job A-Rod!''

Ne-Yo praised Rodriguez as Lopez's ''biggest fan'' and claims she transforms whenever Rodriguez visits her on the set of World of Dance.

He added: ''He comes on set from time to time. He's super fun. He's her biggest fan, which is great, and she lights up.

''She already lights up a room when she walks in, because it's just J. Lo and that's what she does, but when he comes around it's like, 'OK, [put on your] sunglasses. We get it - you guys love each other and you're happy. Alright, we understand.' It's a beautiful thing to observe.''
