Jessie J felt it was "her duty" to write Justin Bieber a letter when he was going through his recent turmoil.
The 20-year-old heartthrob has been at the centre of many scandals over the last year, getting arrested for DUI, lashing out at photographers and being caught on camera using racist language.
Stars such as Usher and Russell Brand have weighed in on his antics, with Jessie, 26, the latest to ask fans to give Justin a break.
"I just felt like it was my duty," she told British newspaper The Sun of the letter she penned. "I hand-wrote it old school. I was just like, ‘I’m here. You’re amazing.’ He’s f**king young and he’s got so much pressure on him."
The British singer explained that while people think they understand what stars are going through, it is impossible. She cited having her photograph taken as a prime example of things not being as they seem.
"When it’s just a picture of us, you’re not seeing the hundreds of people pushing you, kicking you and hurling abuse at you," she said
“Sometimes even the people you may frown upon, whose behaviour you may frown upon, they’re the ones that need the most help."
Although Jessie put a lot of effort into the note, in the end she didn't send it. The star decided that she didn't know Justin well enough to offer advice, so instead reached out to his people and sent a message saying she was there for him if needed.
This wouldn't be the first time the singer has acted as a mentor - she appeared as a judge on the UK version of The Voice in 2012 and 2013. She's proud of her stint, even though she was criticised for being too over the top.
In fact Jessie has been offered a role on the British version of The X Factor, although she told Simon Cowell it wasn't for her.
"He has offered me X Factor twice. I think the show’s been a major success and loads of amazing acts have come out of it but I can’t handle the whole taking the p**s out of people," she said.
“I can’t sit and watch them putting people through for TV amusement and I said that to Simon’s face when I sat with him. I said, ‘I appreciate you as a businessman but I’m not a bully - and it’s bullying.’”
