Selena Gomez calls Jennifer Aniston when she needs advice.

The 23-year-old star feels ''very lucky'' to be friends with the 'Cake' actress, 46, because she is so ''kind and warm'' and helps to guide her through life.

She said: ''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.''

As well as Jennifer, Selena is also thankful for her friendship with ''loyal'' Taylor Swift, 25, who is always able to give her reassurance on her personal and professional life.

She told LOOK magazine: ''Taylor is such a great friend. She's the most loyal friend anyone could ever have.

''She was one of the first people to see my video for 'Good For You' and she was so thrilled and told me how amazing it was and how excited she was for me.''

She added: ''There's always some doubt in the back of your mind about whether you're moving in the right direction musically and Taylor is so smart and has very good instincts about music and videos. It meant so much to me to know that she really liked it.''
