Selena Gomez is such a liar. So states Ellen DeGeneres during an interview that will air today. Joking around with the young singer, the comedian pulls out a clip from a few months ago, one in which Selena laughs off rumors about dating Justin Bieber by referring to him as akin to a "little brother." Ellen DeGeneres gifted Selena Gomez with the ultimate present: a Justin Bieber pillow. "He's not like your little brother, is he?" Ellen asks the blushing star. "No, he's not. And he's a fantastic guy. You can't try to hide that forever." This is the second time this month that Gomez has been faced with questions about Bieber on a national talk show.
