Sounds like they had quite a reunion in the Bahamas!
Justin Bieber's ex-girlfriend Caitlin Beadles (who splits from the Biebs when his career took off) was Tweeting about her getaway in the Bahamas with the teen singer, even though their trip was supposed to be kept a secret.
She Tweeted, "What happens in the Bahamas stays in the Bahamas" about a week after their trip and just five days ago she added, "I hate when you have to leave. It's like half of me is gone. I miss you already!"
It's the sound of little tween hearts breaking all over the world!
