Selena Gomez revealed her new music will be different from her other ‘sad girl songs’ on Monday’s episode of The Tonight Show Starring Jimmy Fallon on NBC.

‘I’m just so used to writing sad girl songs because I’m good at that, but I’m ready to have some fun,’ Selena said. ‘And I think people are going to like it.’

Selena, 30, appeared on the show wearing a black dress to promote her Apple TV+ documentary film titled Selena Gomez: My Mind & Me. Selena said she started filming the documentary around seven years ago.

‘We kind of went through all the different phases of my life from getting diagnosed and doing all the things that I had to go through,’ Selena said. ‘Not going to lie, I can’t watch it. To be honest, I was scared to release it, but knew that being honest and being completely transparent was what I wanted to be known for. I don’t want to be an unattainable thing. I want people to know that it’s not just you and that they’re not alone.’

Jimmy, 48, asked her about going to White House and meeting with President Biden and the First Lady to discuss mental health issues.

‘That was just a conversation,’ Selena said. ‘I hope that there is more that is going to be happening. But it was really incredible to be there with a bunch of young people discussing mental health and the crisis that we are in.’

Selena said doing charity work helps her feel like she has a purpose.

‘In some ways, I feel selfish because I want to do more but I do know that I won’t stop this fight until the day I die,’ Selena said. ‘I think mental health is incredibly important and should be focused on.’

Jimmy said he loved the part in the documentary where she went to her hometown and her old house and there was an actual mirror she had written the name Cole Sprouse, her The Suite Life of Zack & Cody co-star, and drew a heart next to his name.

And my first kiss was his brother,’ Selena noted. ‘On TV.’

‘I think I felt much better that it wasn’t him because I would have been an idiot,’ Selena said.

Jimmy also asked Selena about her sense of humor and why she named her kidney.

‘So I got a kidney transplant a couple of years ago and as a way of coping, I thought I would name it,’ Selena said. ‘It’s weird. I know, but I did and I named it after Fred Armisen.’

Jimmy asked her why.

‘Because I love Portlandia and I love everything he does,’ Selena said referencing the comedian’s TV show.

Jimmy asked if Fred knew.

‘Yeah, he sent me flowers,’ Selena said.

Jimmy told Selena that her Hulu show Only Murders In The Building was one of his favorites.

‘I have so much fun working with Steve [Martin] and Marty [Short],’ Selena said. ‘It’s honestly a dream. They are incredible.’

Selena said they will start shooting season three in January.

She also played an Egg Roulette game with Jimmy at the start of the show.

They each took turns smashing an egg from a carton against their forehead without knowing if it was hard-boiled or raw with the first to smash two raw eggs losing.

Selena took the first egg and smashed it on her forehead but it was cooked. Jimmy went next and ended up smashing a raw egg against his head.

‘I don’t feel good about this one either,’ Selena said when she took the next egg.

The egg she grabbed was raw and the yolk messed up her bangs. Selena’s final egg was also raw and cracked all over her hair as she screamed in disgust.
