Billy Ray Cyrus thinks Miley should reconsider quitting Twitter.
Shortly after the Disney star, 16, signed off the micro-blogging site because her boyfriend, Last Song costar Liam Hemsworth, doesn't approve, Billy Ray, 48, posted a plea for her return.
"Miley. You are light in a world of darkness. You were born 'Destiny Hope Cyrus' for a reason.You can't leave everyone now. We r countin on u," he wrote.
Shortly after, he added: "it is true one bad apple spoils the bunch". But listen to the words of your songs 'Stand... for what ya believe in'...Remember?"
An hour later, he wrote: "Words can hurt worse than bullets True.All the more reason to take this tool and tweet 'I'm comin to Chicago and askin kids to stop killin kids.'"
Miley -- who had more than 1.1 million followers -- posted her final Tweet on Thursday.
"FYI Liam doesn't have a Twitter and he wants me to delete mine with good reason," she wrote.
The Hannah Montana star has used Twitter to support gay marriage, plan gatherings with Spencer Pratt and Heidi Montag and complain about her sore throat.
Her mom (and Billy Ray's wife), Tish, also quit the site, but Miley's sister, Brandi, and brother, Trace, are still active.
Miley's dad isn't the only star mourning her absence from the Twitterverse. Heidi Montag Tweeted Thursday afternoon, "@mileycyrus come back! twitter misses u!"
