Gomez responded to the question by starting off with, "here's a random story that I've actually never told anyone."

"I went overseas to visit my ex-boyfriend while he was on tour and we were in this place that I've never been and this guy comes in," the Come & Get It singer said. "And he's, like, an emperor. He goes up to Justin and is like, 'here I wanna give you this $3 million diamond to give to Selena.' "

The radio crew was floored with Gomez's story and she further explained by saying about the diamond "it was his wife's!"

"They collect them cuz they're millionaires. It was the craziest thing," she said.

One of the radio jockeys asked if Bieber took the gem, but Gomez replied, "No, no, no, no, no."

"We saw it...it was just a gift cuz they were so giving there. They were giving us food and tea, and it was just really great...I didn't accept it."
