The 23-year-old star said the "Cake" actress, 46, is kind and warm," reported Female First.
"I met Jennifer through my management company - we're represented by the same people - and she's been so wonderful to me. She's invited me over to her house and made pizza for me and just been so kind and warm.
"I'm very lucky to have her as a friend and we've talked a lot about dealing with the media attention and having your life exposed at times. I know I can call her for advice and that's a nice feeling," said Gomez.
