Selena Gomez [1] and Jennifer Aniston [2] could not stop gushing over each other when the actress guest-hosted [3] The Ellen DeGeneres Show on Friday. "Rachel was my life!" Selena told Jennifer while discussing Friends [4]. "I cried when the whole season was over, but what made me so happy is now people my age and everyone else is just obsessed and it just makes me so happy for you and for the show because it's iconic."

"You've always been so sweet. You really are a genuine fan," Jennifer said. "It's amazing. We've known each other for years. You've been to my house, we've had pizza, girl after my own heart." Selena then reflected on the time she first met Jennifer in a bathroom and totally freaked out, before diving into her new album [5], Rare, which recently hit No. 1 on Billboard's Artist 100 chart [6].
