Appearing on “Ellen” on Tuesday, Selena admitted she was completely starstruck when she met Pitt at the 2013 MTV Movie Awards on Sunday.
The 20-year-old revealed, "I was in my dressing room and I had just finished performing. And they knocked on my door, and they said Brad Pitt would like to come in. And I was like, 'Well, he can come in!'"
Gomez added, "I was trying to play it cool and be really nice… as soon as he walked out, I ran and I hid under the craft service table for like two minutes because I couldn't believe it was happening."
Pitt had stopped by to ask to take a photo with her for his kids, who are apparently fans of her show, "Wizards of Waverly Place."
