Selena Gomez's words about the Biebs are coming back to haunt her!

On the Ellen DeGeneres Show Tuesday, the actress-singer, 18, got teased for what she used to say about her secret boyfriend Justin Bieber.

Ellen DeGeneres played an old clip of Gomez shrugging off romance rumors about Bieber, 17. "He's like my little brother. That's weird to me," Gomez said during her previous appearance on the show.

Giggling on Tuesday's show, Gomez didn't have a good answer for how to describe her relationship nowadays. "Don't take me to jail!" she said. "I don't know! I don't know."

"Now you've made [the relationship] public," DeGeneres pointed out. "[You've] made me a fool."

Laughing, Gomez retorted: "No, I really didn't...He's just sweet!"

DeGeneres continued to grill her good-naturedly. "He's not like your little brother, is he? No, he's not. And he's a fantastic guy. You can't try to hide that forever. I know you all were sneaking around but that's crazy. You're both huge stars and you can't hide from us!"

"I didn't lie to you," Gomez insisted. "I didn't though. I'll say that."

"No, you didn't blatantly lie," DeGeneres said. "[But] a little brother is not someone you want to date."

"Well, no," Gomez admitted. "That would be weird."
