How to comfort a girl ?

My sister is obsessed with this rock band she's been listening to she's in love with the bass player she has an obsession with him. She cries about him a lot even if it's over something stupid. He's 58 years old he's married to a girl whose around her age she said it's not fair. Even though he's almost 60 he still looks like he's 20 or 30. He lives in another country his band doesn't tour much here anymore he has a solo album coming out she's hoping that means he'll do a tour it's upsetting her knowing she'll probably never see him she can't afford to go to the country. She's upset because his wife posted a video of him shirtless she wishes she was married to him she doesn't care how old he is. She's pretty upset right now I can't get her to stop crying. He had his own TV show a while back it was on Netflix it's now on YouTube she was gonna watch it now she doesn't want to I tried giving her snacks like her favorite chips she said she's not hungry she said she's not feeling good. Times like this when she's
really sad or depressed she wished she could talk to him but she's shy she's not good with talking to celebrities. How can I calm her down ? What should I say to her ? Is it ok for me to cuddle with her ?
