Jenny from the Block has a new boo and doesn't care who knows it... or does she?

J.Lo and new boyfriend Alex Rodriguez are currently enjoying a romantic vacay in the Bahamas, and the songstress posted - then deleted! - a pic of the baseball star nibbling on her ear! Some people are saying the relationship is just for publicity, but it seems this is the real deal.

So how did the new couple make a love match?

"Alex and Jennifer ran into each other about a month or so ago in L.A. They're both single, have these huge careers and their families are their No. 1 priorities. They have a lot in common and friends thought they could be really good together," a source dished to Entertainment Tonight.

"Jen flew to Miami with her kids. She dropped them off there and she and Alex then took their first trip together to the Bahamas to get away. Their schedules are so crazy and that isn't going to slow down anytime soon. They will both continue to carry out their work obligations and will meet up when time allows," the source added.

We bet Drake is kicking himself for letting her get away!
