Drake Bell often uses his Twitter account to engage in feuds with other, better known celebrities.
Over the years, he's gotten into it with stars such as Justin Bieber (along with the singer's passionate fans) and Caitlyn Jenner, among others.
Over this past weekend, however, Bell was in no mood to feud.
He was simply stunned and sad over the death of Stevie Ryan.
According to the Los Angeles Coroner’s office’s, the viral video star and aspiring actress hanged herself in her home on July 1.
While details continue to pour in and while we may never know what drove Ryan to commit this tragic act, her final Tweet was posted just a day earlier.
And it was in remembrance of her grandfather.
"The man of my dreams will now only be in my dreams," she wrote. "I'll miss you everyday, forever. I love you my Pa."
Ryan was clearly in a very low place at the time.
Bell, meanwhile, dated Ryan - a YouTube star perhaps best known for her celebrity impressions - from 2005 to 2006.
They attended the 2006 MTV Movie Awards together, walking the red carpet and posing for photographers.
"No no no!!!! I can NOT BELIEVE THIS IS HAPPENING!!!! Please wake me from this nightmare @StevieRyan I loved you and will forever miss you!" wrote Bell in response to the awful news on Sunday.
He later linked to a Fox News report on Ryan's passing and added:
"This is too much. My heart is crushed. @StevieRyan I love you and miss you..."
A short time later, Bell re-Tweeted a video of Ryan and Perez Hilton from 2007, quoting the celebrity gossip blogger, who wrote that he was "sending so much light to [the loved] ones" of the late 33-year old.
Ryan was outspoken about her struggle with depression over the years on social media.
She even created and co-hosted a podcast about the mental illness called "Mentally Ch(ill)" with Kristen Carney.
Along with a few broken heart emojis, Carney Tweeted the following in response to Ryan's suicide:
RIP @StevieRyan. The coolest girl I've ever known.
The California native sky-rocketed to fame on YouTube thanks to her impersonations of stars such Kim Kardashian, Amy Winehouse and Justin Bieber.
She then starred her own sketch comedy show on VH1, "Stevie TV," and co-hosted a relationship program ("Sex with Brody") with Brody Jenner.
She was reportedly found unresponsive at her home on Saturday and pronounced dead at the scene.
Bell may have actually dated Ryan, but he wasn't alone in mourning her death.
Here's a look at a few other responses to her shocking suicide:
If you or a loved one are struggling with depression, please seek professional help.
If you are having suicidal thoughts, please call the National Suicide Prevention Lifeline at 1-800-273-8255.
